Polymeric materials with a polyvinyl chloride and polyester-carbonate base

摘要

The present invention relates to polyvinyl chloride (PVC)-based polymeric materials comprising polycaprolactone (PCL) derivatives in which the polycaprolactone (PCL) derivatives contain segments of polycaprolactone (PCL) with a molecular weight of between 500 and 15,000, linked or unlinked to segments of polyoxyethylene glycols (PEGs) or polyoxypropylene glycols with a molecular weight of between 188 and 4,000, said materials being defined by the following general formula: <CHEM> Where: n is a number between 4 and 135; z is a number between 5 and 300; r is a number between 200 and 20,000.
