An object is to provide a flooring material which, when applied, is satisfactory in applicability and conformability to the substrate and which combines all of various properties required of flooring materials, such as nonfouling properties, marring resistance, and flexibility. The flooring material comprises synthetic resin A, which comprises a polyethylene resin and/or an ethylene/α-olefin copolymer resin, synthetic resin B, which comprises a flexible ethylene-based resin, and synthetic resin C, which comprises a thermoplastic elastomer, and has: a face layer formed from a synthetic resin composition obtained by compounding ingredients comprising 30-60 parts by weight of synthetic resinA, 10-50 parts by weight of synthetic resin B, 10-40 parts by weight of synthetic resin C, the sum of the resins A, B, and C being 100 parts by weight, 1-15 parts by weight of a viscosity improver, and 150-500 parts by weight of a filler; and a groundwork layer formed from a synthetic resin composition obtained by compounding ingredients comprising 0-30 parts by weight of synthetic resin A, 30-60 parts by weight of synthetic resin B, 41-60 parts by weight of synthetic resin C, the sum of the resins A, B, and C being 100 parts by weight, 1-15 parts by weight of a viscosity improver, and 150-500 parts by weight of a filler.
摘要:
An additive-containing molded polyester resin in which the additive hardly oozes out or volatilizes off and can retain its performance for long and the polyester resin is inhibited from suffering a decrease in molecular weight and hence from impairing properties of the composition; and a process for producing the additive-containing molded resin. The process comprises using an extruder (1) or the like to heat and melt a polyester resin (5) and mold the melt into a given shape, during which an additive (6) having two or more functional groups of at least one kind selected among hydroxyl, carboxyl, and amino groups and ester bonds is added to react the additive (6) with polymer molecules of the molten polyester resin (5). Thus, an additive-containing molded resin (50) is obtained in which the additive (6) has been bonded to polymer molecules through ester or amide bonds.

A conductive article includes a substrate and a conductive layer that is formed on the surface of the substrate and contains fine conductive fibers that are dispersed in the conductive layer. One end of the fibers is fixed to the substrate and other end of the fibers protrude from the top surface of the conductive layer. Alternatively, a middle portion of the fibers may protrude from the top surface or fixed to the substrate. Even though the fibers are dispersed well enough to avoid the aggregation of the fibers, portions of the fibers are located close to each other enough to provide electrical contact.

Vinyl chloride resin moldings having excellent fire-retardant property, which have good antistatic property and can prevent adhesion of dust. The molding has an antistatic layer containing a conductive material laminated on at least one side of a base layer comprising a vinyl chloride resin, wherein the base layer has a titanium compound; the base layer has a molybdenum compound; the base layer has a vinyl chloride resin having a specific chlorination degree; the base layer has a phosphorus fire-retarding agent and/or a chlorinated polyethylene; etc.
摘要:
A polymer for imparting functions such as ultraviolet absorbing property and flame retardancy to a condensation system, particularly a synthetic resin comprising an aromatic ester-based polymer and vinyl-based polymer, and a production method thereof are provided, and a modifier using such a functional polymer like that is consequently provided. There is provided a copolymer to which functions are imparted by block-copolymerizing a radical polymerizing function imparting monomer to a polyazo compound comprising a condensation-type or vinyl-based polymer segment and an azo group at a repeating unit using said azo group as a radical polymerization initiator, and this copolymer is used as a modifier for the other synthetic resin.
摘要:
A high bending strength and high density material for osteosynthesis, which comprises a biodegradable and bioabsorbable crystalline thermoplastic polymer material, and a high strength implant material, comprising a composite material in which a bioceramics powder of from 0.2 to 50 µm in particle size is dispersed in the polymer material, wherein crystals of the polymer material are pressure-oriented not in a uni-axial direction but basically in parallel with a plurality of reference axes; and a production method by pressure orientation, which comprises preparing in advance a biodegradable and bioabsorbable crystalline thermoplastic polymer material or a dispersed mixture of the polymer material and a bioceramics powder and melt-molding it into a pre-molded material which is then press-charged at a cold temperature into a cavity of a closed type forming mold, thereby obtaining an oriented molding. Since the osteosynthesis and implant materials are dense and high strength oriented moldings having less anisotropy in which crystals are oriented in parallel with a plurality of reference axes, excellent ideal biomaterials can be provided which have appropriate hydrolysis property, can maintain sufficient strength during a period required for bone union and are degraded and absorbed at such a rate that they do not induce inflammatory reactions after healing of the fractured bones so that re-operation is not required.
摘要:
A self-adhesive for percutaneously absorbable preparations comprising segmented polyurethane which can control the solubility and releasability of a wide variety of drugs which are solid at ordinary temperature, wherein the segment comprises an alkylene oxide chain which is liquid around ordinary or body temperature, and either contains both of hydrophilic and hydrophobic alkylene oxide chains or is composed of one or both of these chains and an alkylene oxide chain containing hydrophilic and hydrophobic parts.
摘要:
A functional film comprising a thermoplastic resin substrate having formed thereon a coating layer and a process for its production. The functional film has various improved properties such as heat resistance and is inexpensive and of general-purpose use. This film is produced by baking a thin film of phenol resin, epoxy resin, silicone resin or the like on a thermoplastic resin substrate, and can be utilized as flexible printed wiring board, insulating tape, etc.
