## Abstract Two series of thermoplastic poly(esterโsiloxane)s, based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) as the hard segment, were synthesized by twoโstep catalyzed transesterification reactions in the melt. Incorporation of soft poly(dimethylsiloxa
ABA-type block copolymers containing segments of poly(dimethyl siloxane) and poly(vinyl pyrrolidinone) were synthesized. Dihydroxyl-terminated poly(dimethyl siloxane) was reacted with isophorone diisocyanate and then with t-butyl hydroperoxide to obtain macroinitiators having siloxane units. The per
