Patent

CA 2140155

A homogeneous polymer blend is disclosed containing components A and B. Accordingly A is about 1 to 30% by weight of a rigid, rod-shaped polymer having a persistence length of at least 10 nm and a ratio of molecular length to molecular diameter of at least 30, and B) is about 70 to 99% by weight of a flexible polymer which contains at least one member selected from the group consisting of non-ionic polar groups, ionic groups and groups convertible into ions. The flexible polymer is any one of polyolefins, polyacrylates, polyamides and polyurethanes. Component A) contains at least one chemically fixed member selected from the group consisting of non-ionic polar group, ionic group and a group convertible into ionic group, in an amount sufficient to render said A) and B) compatible one with the other.
