摘要：
Sheet-like moldings or foils with anisotropic coefficients of thermal expansion are produced from extrudable thermoplastic polymer molding compositions by filling the thermoplastic polymer molding compositions with lamellar phyllosilicates whose diameter is in the range from 10 to 1000 nm and whose aspect ratio is in the range from 1:5 to 1:10 000 and extruding the filled thermoplastic polymer molding compositions, and then monoaxially or biaxially orienting the extrudate to give sheet-like moldings or foils.
