ABSTRACT:
A filler material for thermoplastic polymers which increases the flexural modulus of the resulting filled system along with increasing the percent elongation to fracture is prepared by mixing a major amount of a mica-like, mineral sheet silicate and a minor amount of an additive such that the resulting surface of the sheet silicate possesses protrusions or nodules.
