PRODUCTION OF MOLDING FROM POLYISOCYANATE POLYADDUCT

Title:

PRODUCTION OF MOLDING FROM POLYISOCYANATE POLYADDUCT

Document Type and Number:

Japanese Patent JPH01121315

Kind Code:

A

Abstract:

PURPOSE: To produce the moldings or films with excellent mechanical properties by thermoplastic molding by making to react aromatic polyisocyanate, suitable compound allowed to react with the isocyanate and diamine or the like.

CONSTITUTION: The polyadduct is produced by blending (A) aromatic polyisocyanate (e.g. 4,4'-diisocyanate diphenyl methane or the like), (B) a compound having molecular weight of 1,800 to 12,000 and containing isocyanate- reactive groups having an average functional value of at least 2.5 freferably 3.0, (C) (i) diamine having molecular weight of 108 to 400 and containing primary and/or secondary amino groups, and (ii) any C component of a group composed of aliphatic polyol having molecular weight of 60 to 1799, and making to react the mixture in, e.g. a one-short process or the like.
