Document Type and Number:
Japanese Patent JP3976359
Kind Code:
B2
Abstract:
The present invention relates to aspartate-functional hydantoin prepolymers prepared by reacting a polyisocyanate having a functionality of at least 1.8 with a polyaspartate corresponding to the formula wherein X represents an organic group which has a valency of n and is inert towards isocyanate groups at a temperature of 100 DEG C or less, and R1 and R2 may be the same or different and represent optionally substituted hydrocarbon radicals, R3 and R4 may be identical or different and represent hydrogen or organic groups which are inert towards isocyanate groups at a temperature of 100 DEG C or less and n has a value of 2 to 6, preferably 2 to 4 and more preferably 2. The present invention is also directed to compositions suitable for the production of coatings, adhesives, elastomers, potting compounds or composite matrices containing these polyhydantoin prepolymers in combination with optionally blocked polyisocyanates.
