Internally plasticized vinyl chloride polymers and process for their manufacture

摘要

An internally plasticized vinyl chloride polymer with a polycaprolactone content ranging from 32 to 40% is prepared by polymerizing vinyl chloride in the presence of polycaprolactone. The graft copolymers show good transparency, homogeneity, and processing properties. The copolymers of the present invention can be used to produce materials used in medical applications, such as, blood bags and dialysis tubing.
