摘要:
An aqueous dispersed polymeric composition for preparing the spill resistant carpet backing is provided. The aqueous dispersed polymeric composition of the present invention comprises an aqueous dispersed polymeric material, an inorganic filler, and a hydrophobic compound selected from the group consisting of a hydrophobic acid, a salt of a hydrophobic acid, and mixtures thereof. Alternatively, the inorganic filler is pretreated with the hydrophobic compound. Also, a kit and a method for preparing a spill resistant carpet backing from the aqueous dispersed polymeric composition is provided.
摘要:
The present invention provides a unitary run flat tire (RFT) reinforcement using filament material that is formed into a relatively rigid shape. The reinforcement is insertable into a mold for an RFT support and can maintain the needed structural rigidity for such insertion. Further, the invention provides an RFT support that is molded and includes the RFT reinforcement. The invention also provides a wheel assembly including a tire, a rim, and an RFT support between the rim and the tire, where the support includes the RFT reinforcement. The RFT support can have a colored indicator formed or subsequently applied thereto to indicate one or more attributes of the support.
摘要:
The presently disclosed and/or claimed inventive concept(s) relates generally to oligomeric reaction products formed by the depolymerization of polyethylene terephthalate polymers and methods thereof. More specifically, the presently disclosed and/or claimed inventive concept(s) relates to oligomeric reaction products formed by the depolymerization of polyethylene terephthalate polymer obtained from, for example but not by way of limitation, waste products, such as beverage containers made from polyethylene terephthalate (PET). The oligomeric reaction products can, in one embodiment, be used as a starting material for polyurethanes. The presently disclosed and/or claimed inventive concept(s) also relates to processes for producing oligomeric reaction products from the depolymerization of polyethylene terephthalate. More particularly, the presently disclosed and/or claimed inventive concept(s) relates to a process of producing oligomeric reaction products of polyethylene terephthalate capable of controlling the removal of byproducts during the reaction. The presently disclosed and/or claimed inventive concept(s) also relates to ultraviolet curable urethane acrylate and polyethylene terephthalate compositions and methods of making and uses thereof.
摘要:
Claimed is a substrate having a polar surface and, adherent thereto, a polyurethane polymer which was applied as a latex. The latexes of the present invention are chain extended in water with aminoethyl ethanolamine and are prepared and applied in the substantial absence of organic solvents. The prepolymers used to prepare the latexes are substantially free ionic groups on the polymer backbone.
摘要:
The present invention is polyurethane dispersion composition that can be mechanically frothed to yield a foam that has good resiliency. Frothed foams of the present invention can be useful in cushioned flooring applications such as attached cushion broadloom, carpet tiles, carpet underlay, or vinyl flooring. Frothed foams of the present invention can also be useful as coatings for various textiles and for diapers.

摘要:
Disclosed are stable aqueous polyurethane latexes prepared from prepolymer formulations including a polyisocyanate component and polyol component, wherein from 5 to 40 percent of the weight of the polyol component is ethylene oxide in the form of ethylene oxide applied as an end cap onto a propylene oxide or higher oxyalkylene polyoxyalkylene polyol, and no more than 45 percent of the weight of polyol component is ethylene oxide. These latexes are prepared without the use of organic solvents.
摘要:
A polyurethane/urea/thiourea latex having a narrow molecular weight polydispersity and sub-micron particle size can be prepared by first preparing a high solids (between about 65% and 74% solids) latex of a polyurethane/urea/thiourea prepolymer, then contacting the emulsion with a chain-extending reagent under such conditions to form the polymer latex.
