ABSTRACT:
A homogeneous polyolefinic blend and a preparation process thereof, are provided wherein the blend comprises polyolefin and a polymer which has a barrier property to organic liquid and vapor permeability. The barrier property is improved through the inclusion of mixed compatibilizing substances comprising an alkylcarboxyl-substituted polymer and reactive low molecular weight compounds. The compatibilizing substances are included by the means of ordinary processing equipment. The polymer with the barrier property having low organic liquid and vapor permeability is distributed as a multitude of thin, wide, disc-like layers in a polyolefin phase. The compatibilizing substances minimize the interfacial energy between the two polymers to adhere them together.
