Abstract
PURPOSE: To obtain a polymer having improved plasticizer absorptivity, fish eye level, etc., by reacting a proteolytic enzyme obtained from high-temperature active bacteria with a vinyl type polymer prepared by polymerization in the presence of a gelatin type dispersant.
CONSTITUTION: A polymer which is freed from a conventional defect that a vinyl type polymer prepared by polymerization in the presence of a gelatin type dispersant has poor plasticizer absorptivity and fish eye level and the mechanical properties after processing is not good, is obtained by reacting a proteolytic enzyme obtained from bacteria which can multiply without fail in culture conditions of 50°C or higher (for example, proteolytic enzymes obtained from bacteria such as Bacillus licheniformis and Bacillus thermoproteolyticus Rocco) with a polymer obtained by polymerizing a vinyl type monomer such as a vinyl chloride monomer, a styrene monomer or its mixture with a copolymerizable comonomer.
