The compositions of the invention include discreet continuous phases of matrix resin and additive resin, with the filler material being present essentially entirely within the additive resin phase (i.e., essentially absent from the matrix resin phase). More specifically, the components are selected so that their respective surface tensions allow the additive resin to form a complex three-dimensional interpenetrating network structure within the matrix resin when melt-blended, and such that essentially all of the filler material is homogeneously dispersed throughout the formed three-dimensional network structure.

Abstract: Polyacetal compositions are made by melt-blending a polyacetal base resin A, a filler material B, and a thermoplastic acrylic resin C in weight ratios which satisfy the following formulas (1) and (2):(B+C)/(A+B+C)=0.03 to 0.06 (1)C/(B+C)=0.05 to 0.95 (2).The thermoplastic acrylic resin C is most preferably selected from homopolymers of methyl methacrylate or copolymers which are mainly comprised of units derived from methyl methacrylate. The melt-blending of the polyacetal base resin A with the thermoplastic acrylic resin C is accomplished in the presence of a filler material B having a surface tension which is greater than that of the thermoplastic acrylic resin C at the melt-blending temperature. In this manner, a continuous phase of the thermoplastic acrylic resin is formed in a matrix of the polyacetal base resin such that the filler material is encapsulated in the continuous acrylic resin phase.
