Abstract

A series of soft to tough copolymers have been prepared by the cationic copolymerization of the modified linseed oils Dilulin or ML189 with DCPD. Soxhlet extraction and solid‐state ^13^C NMR spectra indicate that the bulk copolymers consist of a cross‐linked oil/DCPD network interpenetrated with certain amounts of soluble components. The T~g~s of the resulting Dil/DCPD and ML189/DCPD copolymers are in the range 15–83 and 8–77 °C, respectively, and increase linearly with the increase of the DCPD amount. The room‐temperature storage moduli range from 4.43 × 10^6^ to 1.52 × 10^9^ Pa for the Dil/DCPD copolymers and from 3.72 × 10^6^ to 1.44 × 10^9^ Pa for the ML189/DCPD copolymers.

## Abstract A series of various soybean oil/dicyclopentadiene (DCP) thermosetting copolymers with renewable carbon percentages of 53–86% have been prepared by cationic copolymerization of regular (SOY) or 100% conjugated soybean oils (C~100~SOY) with DCP initiated by NFO ethyl ester modified and SO
