  • TDI prepolymers with improved processing characteristics
    Publication number: 20070135607
    Abstract: The present invention relates to novel prepolymers of toluene diisocyanate and to a process for the preparation of these toluene diisocyanate prepolymers. This invention also relates to a process for the production of a polyurethane backing or a frothed foam backing on a substrate, and to a process for forming a layer of blown, cellular urethane foam on a suitable substrate. These novel prepolymers comprise toluene diisocyanate prepolymers with a small quantity of an epoxide.

  • Process for the production of carbodiimide modified organic isocyanates
    Publication number: 20050282993
    Abstract: 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.
