ABSTRACT:
Seamless, molded, thermoplastic articles having a laminar, multi-component composition with a heterogeneous blend of incompatible polymers--at least one as a matrix and at least one as a discontinuous phase, are manufactured by (1) heating the blend above the melting point of the highest melting polymer component, and (2) molding the melted blend to have a knit line curved through the thickness of the article resulting from such molding.
