Abstract:
1. A graft copolymer composition comprising a hydrolizable silane graft propylene-α-olefin copolymer, the composition comprising: a hydrolizable silane graft propylene-α-olefin copolymer comprising a propylene-α-olefin copolymer component and a hydrolizable silane component, and from 0.1 to 5 wt %, based on total weight of the hydrolizable silane graft propylene-α-olefin copolymer, of at least one silanol condensation catalyst: wherein the propylene-α-olefin copolymer component comprises propylene-derived units and from 5 to 20 wt %, by weight of the propylene-α-olefin copolymer, of ethylene-derived units or C (i) a density of from 0.850 to 0.920 g/cm (ii) a MWD of from 1.5 to 20; (iii) an H (iv) a T (v) a triad tacticity by (vi) a melt flow rate (2.16 kg, 230° C.) of from 0.2 to 100 dg/min; (vii) a weight average molecular weight of 50,000 to 400,000; and (viii) a number average molecular weight of 25,000 to 200,000; and wherein the cured graft copolymer composition comprising the hydrolizable silane graft copolymer has an Elongation at Break as determined by ISO-37 (500 mm/min, 23° C.) greater than 400%; wherein the hydrolizable silane component is derived from a vinyl silane having the following formula: YSiRR″ wherein the graft copolymer has a haze value of from less than 15%.
