KR950011491A - Reactive compatibilizers and resin compositions containing them - Google Patents

Abstract

A structure that has a functional group capable of reacting with the first resin to promote compatibility with the first resin and also has a chain or functional group compatible with the second resin to achieve compatibility with the second resin. Reactive compatibilizer and a resin composition containing the same to increase the compatibility of two or more incompatible resins to make a useful blend.
