Synthesis and characterization of polycarbonates containing terminal and chain interior siloxane
Silicone polycarbonates having polydimethyl siloxane (PDMS) and heptamethyl trisiloxane (HMTS) were synthesized by the interfacial polymerization. Instead of common chain terminator p-tert-butyl phenol (PTBP), eu...

Synthesis and characterization of branched bisphenol-A polycarbonates functionalized with siloxane
Branched and grafted silicone polycarbonates were synthesized from branched allyl polycarbonate (Br-Allyl-PC) precursors and siloxanes by a controlled hydrosilylation reaction using Karstedt’s catalyst. The Br...

Preparation and characterization of imide-grafted poly(ethersulfone)s
Poly(ethersulfone)s carrying pendant imide side group with a low dielectric constant were prepared. The first step in the preparation involved the nitration of poly(ethersulfone) (ultrason®-S6010), with ammoni...
