Oligomer, oxazolidinone gp. and isocyanurate gp. contg. polyepoxide(s) - prepd. from bis:epoxide(s) and di:isocyanate(s), have improved impact and breaking resistances, etc.

摘要

Oligomer oxazolidinone gp. and isocyanurate gp. contg. polyepoxides from bisepoxides and diisocyanates are new. In bisepoxides include cpd. of formula (I). ADVANTAGE - The hardened prods. have increased breaking resistance, elongation at break and impact resistance compared to oxazolidine-free prods.
