Abstract
Cyclopentadiene was polymerized via a Diels-Alder mechanism at 174°C under an inert atmosphere. The polymer obtained after ll hrs of reaction had a low bulk viscosity of 8 cps and a viscosity-average molecular weight, Mv, of up to 3000. An unsaturated polyester was synthesized from maleic anhydride and ethylene glycol in the presence of chlorosulfonic acid at room temperature. The polyester had an intrinsic viscosity of 0.024 cps. At 60°C, polycyclopentadiene (PCPD), and the unsaturated polyester were reacted to yield a viscous liquid which was crosslinked at room temperature over 48 hours in the presence of styrene, triethyleneglycol dimethacrylate (TEGDMA), N,NI-dimethyl-p-toluidine and benzoyl peroxide. The hard, crosslinked material is thermally stable at 250°C and possesses a high degree of crosslinking in acetone, toluene and dimethylformamide (DMF).
