Firstly,the master batches were made by melt extrusion method,then the pure POE(ethylene-α-olefincopolymer)film(S1),MAH(maleic anhydride)modified POE film(S2)and silane coupler modified POE film(S3)were further prepared by casting film-forming method when POE was used as matrix,peroxide-2-ethyl hexa-estertert-butyl carbonate was used as crosslinker,triallyl isocyanurate was used as assistant crosslinker,vinyl trimethoxysilane was used as silane coupler,and MAH was used as modifier. The research results show...
