Abstract

A latex or fiber comprising a blend of polymeric materials consisting of one or more &agr;-olefin/ vinylidene monomer non-crosslinked substantially random interpolymers, wherein the distribution of the monomers of said interpolymers can be described by the Bernoulli statistical model or by a first or second order Markovian statistical model, and one or more homopolymers or copolymers of monomer components comprising aliphatic &agr;-olefins having from 2 to 20 carbon atoms, or aliphatic &agr;-olefins having from 2 to 20 carbon atoms and containing polar groups.
