摘要:
A hydrophilie coating is applied to the surface of a substrate by a method which comprises the steps of (a) applying a first coating comprising a polyvinyl chloride copolymer; and (b) applying a second coating comprising a mixture of a poly(N- vinyl lactam), a polyvinyl chloride copolymer and optionally a zwitterionic compound. Preferably the polyvinyl chloride copolymer is a vinyl chloride-vinyl acetate copolymer. A substrate resulting from the method and a kit for carrying out the method are also provided.

A thermoplastic alloy is disclosed comprising poly(vinyl halide) and an olefin-based uncrosslinked elastomer having thermoplastic properties. The alloy can be made into a polymeric skin using slush molding techniques.
摘要:
Disclosed are plasticizer compositions including cyclodextrin derivatives, a flexible PVC composition with suppression of the migration of a plasticizer containing the same, and a manufacturing method thereof. The manufacturing method of the flexible PVC composition of the present invention includes steps of (Sl) preparing cyclodextrin derivatives; (S2) mixing the cyclodextrin derivatives, PVC and a low molecular weight liquid plasticizer to form a plastisol; and (S3) heating the plastisol to form a solution and cooling the solution. The manufacturing method of the present invention may be useful to mass-produce flexible PVC with suppression of the migration of a plasticizer in a simple and economic manner without using solvents since the cyclodextrin derivatives are used as a compound that can suppress the migration of a plasticizer. The flexible PVC has an effect of reducing an amount of the migrated plasticizer without deterioration in its physical properties.
摘要:
A composite material and a method of making a composite material that includes: a polyolefin; polyvinyl chloride and a compatibilizer, preferably a nanoclay. The polyolefins is preferably polypropylene or polyethylene. In a preferred embodiment, the composite material includes a polypropylene, a polyethylene, polyvinyl chloride and a nanoclay. The nanoclay includes a quaternary ammonium salt based organic group and exfoliates when heated and is most preferably bentonite, smectite, hectorite, sepiolite or montmorillonite.

摘要:
The present invention relates to a denture adhesive article comprising a safe and effective adhesive amount of a denture adhesive component, wherein the denture adhesive article is a sheet that has a concave shape.
摘要:
Disclosed herein are an adhesive sheet and a manufacturing method thereof. The adhesive sheet comprises a polyvinyl chloride sheet formed of a polyvinyl chloride sheet comprising polyvinyl chloride, tourmaline and/or kiyoseki, and a flame retardant. The adhesive sheet may further comprise an antibacterial/deodorant layer formed on one side of the polyvinyl chloride sheet. The adhesive sheet has excellent ability to remove volatile organic compounds (VOCs), and excellent flame retardancy and printability.
摘要:
A composition for stabilising halide-containing polymers, said composition comprising compounds represented by the general formula (I) wherein X, Y, and Z are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, amino, and groups having the structure (II) wherein R 1 and R 2 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl, phenylalkyl and aryl group, A is oxygen (O) or sulfur (S); and wherein the dashed double line represents an optional double bond.
