Synthesis of Methyl Methacrylate-EPDM-2-vinylnaphthalene (MEVN2) Graft Copolymer

摘要

The present invention relates to a method and a process for producing a thermoplastic resin having excellent weather resistance, heat resistance and light resistance, and more specifically relates to a process for producing 2-vinylnaphthalene (EPDM) having high resistance to heat, ultraviolet rays and oxygen, The present invention relates to a method and a process for the synthesis of methyl methacrylate-EPDM-2-vinylnaphthalene (MEVN2) graft copolymer by graft copolymerizing methacrylate (MMA) with 2-vinylnaphthalene And the reaction was carried out at 60 to 100C for 10 to 90 hours using a 0.1 to 20 wt% starting material of a monomer and the resultant was precipitated in 10 times of cold methanol, filtered and dried in a vacuum drier A method for producing methyl methacrylate-EPDM-2-vinylnaphthalene (MEVN2) polymer having excellent heat resistance after being dried and separated by difference in solubility.
