This invention relates to polyurethane elastomers and to a process for their production. These elastomers comprise the reaction product of a (cyclo)aliphatic isocyanate component having an NCO group content of about 20 to about 45%, with an isocyanate-reactive component comprising one or more polyether polyols which is free of amine groups, and a low molecular weight organic compound containing two hydroxyl groups and which is free of amine groups, in the presence of one or more catalysts.

Fast curing aliphatic RIM elastomers

The present invention is directed to polyisocyanate addition compounds which

Low surface energy, ethylenically unsaturated polyisocyanate addition compounds and their use in coating compositions

The present invention relates to an improved process for the production of carbodiimide modified organic isocyanate, preferably a polymethylene polyphenylisocyanate, and most preferably diphenylmethane diisocyanate. This process includes (1) neutralizing acidic impurities in an organic isocyanate, (2) partially carbodiimidizing isocyanate groups of the neutralized organic isocyanate, and (3) terminating the carbodiimidization reaction.
