Water-absorbent resin dispersion and polyurethane composition

Disclosed herein is a process for producing polyurethane moldings having good physical properties and good receptivity of electrostatic coating, said process comprising reacting a polyoxyethylene chain-containing polyether polyol having 2-4 hydroxyl groups and a hydroxyl equivalent higher than 750 as the high-molecular weight polyol, diaminotoluene and a low-molecular weight polyol having a hydroxyl equivalent of 30-100 as the low-molecular weight, active hydrogen-containing compound, with organic polyisocyanates in specific equivalent ratios respectively. The process may advantageously applied to injection reaction molding.

Process for producing polyurethane

Polymer/polyol compositions, obtained by polymerizing, in situ in a polyol, one or more ethylenically unsaturated monomers comprising an alpha-olefin containing at least 5 carbon atoms and/or an acrylate or methacrylate ester of an alcohol containing at least 9 carbon atoms, which are of relatively low viscosity and which afford polyurethanes having improved properties.

Polymer/polyol composition, processes for making the same and a

Polymer/polyol compositions, obtained by polymerizing one or more ethylenically unsaturated monomers in situ in a blend of a polyether polyol and a polyamine, are of suitably high reactivity. The polymer/polyol compositions provide, by reaction with a polyisocyanate, polyurethanes having improved moldability and physical properties along with self-mold-release characteristics, and are particularly suitable for producing polyurethane by RIM process.

Polymer/polyol composition, processes for making the same and

A flexible polyurethane foam which produces a reduced amount of smoke when in contact with a flame and which has flame resistant properties is produced by reacting, under foaming conditions, a polyetherpolyol having a hydroxyl number of 25 - 80 and, a primary hydroxyl group content of at least 10% and a liquid mixture of a polyoxyethylenepolyol modified polyisocyanate and a polyisocyanate monomer.
