The heat resistance and mechanical performance of polymethyl methacrylate (PMMA) products was im-proved through the changing structure of the molecular chain, using multivariate copolymerization, intramolecular and intermolecular crosslinking methods. Furthermore, heat resistant performance of product was further improved through adding auxiliaries in the product tail. Influence of initial thermal decomposition temperature after adding ethyl acrylate (EA) to the product was emphasized. The heat resistance performance of the synthetic product reaches the requirements.
