Abstract
An aspect of the description is directed to hydrolysable silane graft propylene-α-olefin copolymers useful for moisture curable sealants, the copolymers comprising a propylene-α-olefin copolymer component comprising propylene-derived units and from 5 to 35 wt %, by weight of the propylene-α-olefin copolymer, of ethylene-derived units or a Cto Cα-olefin-derived unit, and having, in one embodiment, the following features: a density of from 0.850 to 0.920 g/cm; a MWD of from 1.5 to 20; an Hof less than or equal to 75 J/g; a Tof from 25 to 105° C.; and a triad tacticity byC NMR of 75% or greater; and a hydrolysable silane component. The graft copolymer can be combined with oil and/or a thermoplastic to form a graft copolymer composition capable of being cross-linked by exposure to moisture.
