Abstract:
An interpolymer comprising:1) from 30 to 70 weight % of one or more monomers selected from the group consisting of C2-10 aliphatic alpha olefins; 2) from 70 to 30 weight % of one or more monomers selected from the group consisting of C8-20 vinyl aromatic monomers which are unsubstituted or substituted by one or more substituents selected from the group consisting of C1-4 alkyl radicals; and optionally 3) from 0 to 10 weight % of one or more monomers selected from the group consisting of C5-9 non conjugated diolefins, wherein said interpolymer; i) contains one or more blocks of three vinyl aromatic monomers in a head to tail to tail insertion fashion (manner) characterized by having a 13C NMR ratio of the areas under the peaks at 38 ppm to 44 ppm of less than 2:1 and multiple peaks between 34 and 35 ppm.
