COMPOUND CONTAINING A THERMOPLASTIC POLYMER AND HYDROPHILISING AGENT

摘要

The invention relates to a method for preparing thermoplastics making it possible to obtain a hydrophilic behaviour of the surfaces of objects made of said thermoplastics. Said invention also relates to used additives, namely to water-soluble or water-dispersible copolyester compounds for producing said surface hydrophilicity, wherein said additives are mixed and comelted with the thermoplastics (additivation into a melt). The melt blends of the thermoplastics and additives are shaped by all conventional means (extrusion, injection, film drawing ) for obtaining desired objects. The applications of said thermoplastic objects to hydrophilic surfaces are also disclosed.
