Polycarbonate-polydimethylsiloxane (PDMS) copolymers were synthesized by interfacial phosgenation of 2,2-bis(4-hydroxyphenyl)propane (bisphenol-A) with different types of PDMS oligomers including a,v-amino-organofunctional polydimethylsiloxane (AT-PDMS oligomer), a,v-hydroxy-organofunctional polydim
## Abstract A new alternating block copolymer was synthesized from dihydroxyβterminated polyβ(ether ketone sulfone) and bis(dimethylamino)βterminated polydimethylsiloxane oligomers. The chemistry and the thermal properties are discussed. Surface chemical composition of films was analyzed by ESCA. Q
