Claims15
A laminar, shaped, article comprising a combination of polyolefin, a condensation polymer incompatible with the polyolefin, and an alkylcarboxyl-subsituted polyolefin wherein the polyolefin is present in the article as a continuous matrix phase and the condensation polymer is present in the article, as a discontinuous distributed phase in the form of a multitude of thin, substantially two-dimensional, parallel and overlapping layers of material embedded in the continuous phase and the alkylcarboxyl-substituted polyolefin is present between the layers and adheres the layers together.
