SALTS OF DEHYDROACETIC ACID AS AN ANTIMICROBIAL FOR PLASTICS

摘要

The invention relates to a method for imparting an antimicrobial characteristic to plastic material and a process for making a plastic product by processing the material. The material is a polymer composition comprising at least one polymer and 5 to 10,000 ppm of a salt of dehydro-acetic acid (DHA) which is stable at temperatures required for processing polymeric compositions. The method for making a plastic product preferably includes blending and/or extruding the polymer composition in a process which includes a temperature of at least about 170 °C.
