ABSTRACT:
A substantially linear segmented copolymer of the formula (MX).sub.n where n is an integer greater than 0 and M is a bivalent organic radical segment of the formula ##STR1## wherein R is hydrogen, C.sub.1 to C.sub.4 alkyl, aryl, or C.sub.1 to C.sub.4 alkyl substituted aryl; A is C.sub.1 to C.sub.4 alkylene; A' is C.sub.1 to C.sub.4 alkylene the same or different than A, phenylene or alkyl substituted phenylene; and y is an integer greater than 0; and X is a bivalent organic radical segment of the formula ##STR2## WHEREIN G is a long chain radical segment of recurring linkages selected from the group consisting of ester and ether; and z is an integer greater than 0 the same or different than y.
