(3,4‐Difuryl‐2,5‐dimethyl)phenyl–polyvinyl silicon oils (DDP–C‐gum) were synthesized by Diels–Alder reaction of polyvinyl silicon oil (C‐gum) with 3,4‐difuryl‐2,5‐dimethylcyclopentadienone (DDCP) in diphenyl ether at reflux temperature under atmospheric pressure. Their structures were characterized by 1 H‐NMR, UV, and IR spectra. Properties such as viscosity, refractive index, color, and thermal stability of some DDP–C‐gums were obtained. © 1995 John Wiley & Sons, Inc.
