Synthesis of Poly(dimethylsiloxane) - Nylon 6 Diblock Copolymers

Abstract

Two diblock copolymers of polydimethylsiloxane and nylon 6 have been synthesized using a macromonomer approach. PDMS was synthesized anionically in THF and terminated with 11-(dimethylchlorosilyl)-N-undecanoyl-1-caprolactam, yielding a macromonomer capable of participating in the ring opening polymerization of caprolactam. This second step was carried out with LiAlH2(OtBu)2 catalyst to activate the caprolactam monomer. Good yields and high molecular weight PDMS and Nylon 6 blocks were achieved. (jes)
