Abstract
Rosin maleic anhydride adduct (RMA)-bisester was prepared by the esterification of chlorinated RMA with hydroquinone. Phenylpyridinylcyclotrisiloxane (D Ph,Py3 ) was synthesized from phenylpyridinyldichlorosilane in the presence of zinc oxide catalyst, and amino group terminated polyphenylpyridinylsiloxane prepolymer was prepared by equilibrium polymerization of D Ph,Py3 with 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane. Rosinimide (PSMR) was prepared from the imidization of RMA-bisester with polyphenylpyridinylsiloxane prepolymer at 120°C for 7 h using γ-butyrolactone/pyridine. It showed that PSMR had better thermal stalbility than rosinimide modified with polydimethylsiloxane.
