Abstract:
A thermally-stable, grafted copolymer E/X/Y-(G) composition comprising monomers E, X, and Y in random order and grafting reagent G, wherein:E is ethylene; X comprises from 8 to 70 weight percent relative to the total weight of E/X/Y and is selected from the group consisting of a C1 to C8 alkyl acrylate, a C1 to C8 alkyl methacrylate, and vinyl acetate; Y comprises about 1 to 4 weight percent relative to the total weight of E/X/Y of a glycidyl containing monomer selected from the group consisting of glycidyl acrylate, glycidyl methacrylate and glycidyl vinyl ether; and G comprises from 15 to 150 percent of a stoichiometric amount with respect to the weight of the glycidyl moiety, of a secondary aminosilane compound of the formula Râ€”N(H)â€”Râ€²â€”Si(ORâ€³)3 wherein Râ€² is a C1 to C6 alkylene group, Râ€³ is a C1 to C6 alkyl group, and R is selected froma) a secondary radical of the formula â€”CHR1R2 wherein R1 and R2 are independently selected from C1 to C6 alkyl or C1-C6 arylalkyl and wherein R1 and R2 may be joined to form a C5 to C9 cycloaliphatic ring; or b) a primary radical of the formula â€”CH2R3 wherein R3 is selected from (i) a C3 to C12 alkyl group, wherein, in the case of a C3 to C6 alkyl group, said alkyl moiety is branched, or (ii) a (C1 to C12 alkyl)-aryl group, wherein R1, R2, and R3 may be unsubstituted or substituted with substituents selected from C1 to C4 alkyl.
