摘要：
Provided are elastic propylene-alpha olefin blocky copolymers. In one form, the elastic propylene-alpha olefin blocky copolymer includes an α-olefin content from 12 to 25 wt % and having a propylene crystallinity less than 30 J/g, a Tm −45° C., wherein said copolymer has blocky propylene segments with r1r2 greater than 1.5, and a process for producing such copolymer.
