摘要： The present invention is directed to polyurethane moldings produced via the RIM process. These polyurethane moldings have excellent reactivity, demold properties (at a 30s demold), and good elongation and tear strength, and comprise the reaction product of an aliphatic polyisocyanate having a viscosity of less than about 20,000 mPa?s at 25.degree.C and a NCO functionality of 2.3 to 4.0 with an isocyanatereactive component comprising b1) a relatively high molecular weight organic compound containing at least one of the groups selected from the group consisting of hydroxy groups and amine groups; and b2) a low molecular weight chain extender selected from the group consisting of diols, triols, primary amines, secondary amines, aminoalcohols, and mixtures thereof; in the presence of a catalyst. The OH:NH ratio of the chain extender is from 1:1 to 25:1.

摘要： Stable finely-divided dispersions of polyureas and/or polyhydrazodicarbonamides in a hydroxylgroup-containing material are made by reacting (i) an isocyanate with (ii) a compound selected from polyamines, hydrazines, hydrazides and mixtures thereof in the presence of (iii) a hydroxyl compound selected from polyethers, polyesters, polyester amides, polycarbonates and mixtures thereof and (iv) a catalyst. The catalyst is a compound which catalyzes the reaction of isocyanate groups with hydroxyl groups. The catalyst is used in a quantity of at least 50 parts per million parts of (i), (ii) and (iii). These dispersions are particularly useful in the production of polyurethanes.
