Procedure

The resulting heterogeneous reaction mixture, which was lumpy and hardened, was neutralized by addition of 15% aqueous tartaric acid solution. The polymer was filtered and a small portion was ground thoroughly. The ground material was extracted with 2-propanol for 24 hrs in a Soxhlet extractor and dried to afford a pale brown solid which was not soluble to any extent in distilled water.
