Blends of α-olefin/vinylidene aromatic monomer or hindered aliphatic vinylidene monomer interpolymers with polyolefins

A latex or fiber comprising a blend of polymeric materials comprising

• (A) from 1 to 99 weight percent of one or more α-olefin/vinylidene monomer non cross-linked substantially random interpolymers, wherein the distribution of the monomers of said interpolymer can be described by the Bernoulli statistical model or by a first or second order Markovian statistical model, and each having been made from monomer components comprising:
• (1) from 0.5 to 65 mole percent of either
• (a) at least one vinylidene aromatic monomer, or
• (b) at least one hindered aliphatic vinylidene monomer corresponding to the formula:
• wherein A1 is a sterically bulky, aliphatic or cycloaliphatic substituent of up to 20 carbons, R1 is selected from the group of radicals consisting of hydrogen and alkyl radicals containing from 1 to 4 carbon atoms, preferably hydrogen or methyl;
• each R2 is independently selected from the group of radicals consisting of hydrogen and alkyl radicals containing from 1 to 4 carbon atoms, preferably hydrogen or methyl;
• or alternatively R1 and A1 together form a ring system;
• or
• (c) a combination of at least one vinylidene aromatic monomer and at least one hindered aliphatic vinylidene monomer;
• and
• (2) from 35 to 99.5 mole percent of at least one aliphatic α-olefin having from 2 to 20 carbon atoms;
• and
• (B) from 99 to 1 weight percent of one or more homopolymers or copolymers of monomer components comprising aliphatic α-olefins having from 2 to 20 carbon atoms, or aliphatic α-olefins having from 2 to 20 carbon atoms and containing polar groups.
