METHOD FOR REFORMING ETHYLENE-PROPYLENE-DIENE COPOLYMER AND REFORMED ETHYLENE-PROPYLENE-DIENE COPOLYMER BY THE SAME

摘要

PURPOSE: A modification method of ethylene-propylene-diene copolymer is provided to modify ethylene-propylene-diene through a simple step through simple process steps. CONSTITUTION: A modification method of ethylene-propylene-diene copolymer comprises: a step of mixing a maleic anhydride-grafted ethylene-propylene-diene copolymer with amine group-substituted polyethylene oxide or amine group-substituted polyethylene oxide or amine group-substituted ethylene oxide-propylene oxide copolymer; and a step of manufacturing (ethylene-propylene-diene)-graft-(polyethylele oxide) copolymer or (ethylene-propylene-diene)-graft-(poly (ethylene oxide-co-propylene oxide)) copolymer by grafting polyethyleneoxide or ethylene oxide-propylene oxide copolymer to the ethylene-propylene-diene copolymer.
