The Effect of Poly (vinyl chloride) and Filler on Technological Properties of Polyester Composites

The paper determines the influence of polymer modifier (poly (vinyl chloride)) and finely dispersed inorganic filler on the elastic-deformation and thermophysical properties of polyester materials. The research discovers the change of deformation modulus, elasticity modulus, high elasticity modulus, surface hardness, Vica heat resistance, and technological shrinkage of modified polyester composites filled with calcium carbonate and aluminum oxide.
