## Abstract Eight new poly(imidesiloxane)s copolymers have been prepared by oneโpot solution imidization method. The polymers are made by the reaction of bisphenolโA dianhydride (BPADA) with four different fluorinated diamines and aminoโpropyl terminated polydimethylsiloxane (APPS). The polymers ar
Novel poly(amide imide)s having inherent viscosities in the range 0.89-1.56 dL/g were prepared by the method of low temperature polycondensation in solution of N,N-dimethylacetamide (DMA) from aromatic diamines and a new monomer: N-[4"-(chloroformylphenyl) -4'-iminobenzoyl] trimellitimide chloride.
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
