Polymer based on renewable materials with improved length - contain reaction prod. comprising tri:glyceride with epoxy and/or aziridine gps. poly:carboxylic acid anhydride and poly:carboxylic acid, useful as metal or polymer, e.g. PVC substitutes for e.g. fibre reinforced board, etc.

摘要

Polymer (P) based on renewable materials contains a reaction prod. (R) comprising: (A) 10 - 90 mass % triglyceride contg. at least 2 epoxy and/or aziridine gps.; (B) 5 - 90 mass % polycarboxylic acid anhydride; and (C) 0.01 - 20 mass % polycarboxylic acid. The prepn. of (P) by mixing (A) - (C) and opt. additives (e.g. filler, catalyst and flame-retardant) and then curing, is also claimed.
