ABSTRACT:
Polymers and copolymers of vinyl chloride having a narrow grain size distribution and a large average mean diameter and a process for the preparation of same in which the polymerization of vinyl chloride is carried out in the presence of a prepolymer composition obtained by polymerization, under high turbulence, of a monomeric composition containing vinyl chloride and acrylic acid or methacrylic acid, an aliphatic ester thereof or a diester of a dihydric alcohol.
