POLYELECTROLYTE FLUORINATED ACRYLIC COPOLYMERS AND RELEASE-AGENT COMPOSITIONS FOR USING IN RUBBER VULCANIZATION

摘要

The present invention refers to a polyelectrolyte fluorinated acrylic copolymer having a tuned number of charges in its backbone, said copolymer being useful to produce a release-agent composition. The present invention also refers to a method for obtaining said polyelectrolyte fluorinated acrylic copolymer as well as to a method for producing said release-agent composition. The preferred application of said release-agent composition is in the manufacturing process of vehicle tyres, specifically during the vulcanization of pneumatic rubber vehicle tyres for defining the tyre tread pattern and configuration of the sidewalls thereof.
