Abstract
Dispersions of polymer systems comprising two normally incompatible polymer networks, one of which is held together by physical interactions and the other by chemical cross-links, the networks being catenated, are useful for making coating compositions, films and molded articles.
Claims4
A dispersion consisting essentially of a continuous phase of a compatible organic liquid carrier and a dispersed phase of a system of two or more normally incompatible polymers, the system comprising
- (a) networks of polymer chains, segments of which are held together by physical interactions, and
- (b) networks of chains of one or more chemically cross-linked polymers,
- the networks of (a) and (b) being catenated.
