Abstract

A segmented polymer consisting essentially of a plurality of intralinear structural units of the formula <FORM:1005047/C3/1> wherein m and n are positive integers; G is a long chain polymeric radical free from substituents reactive with an isocyanate and having a M.W. above 950; and R is p,p1-methylene - diphenyl, p,p1 - isopropylidene-diphenyl, p,p1 - oxydiphenyl, p,p1 - thiodiphenyl, or the foregoing radicals having methyl or ethyl as ring substituents. The above polymer may be prepared by reacting a hydroxyl terminated polyether or polyester of M.W. above 1000 with an organic diisocyanate in a molar ratio of between 1.7 and 2.2 : 1 to provide a prepolymer of M.W. above 1500 which is then reacted with m-xylylenediamine. In a typical Example (1) the reaction product of excess p,p1-methylene diphenyl diisocyanate and polytetramethylene ether glycol is diisolved in N,N-dimethylacetamide and reacted with m-xylylenediamine and diethylamine and the solution dry-spun to produce elastic filaments. Specification 849,154 is referred to.
