摘要

Procedure for obtaining an Inert support of crosslinked Copolymer capable of Absorbing and then gradually Release active substance. Involves the polymerization of a monomer mixture that consists of 30 to 80% of acrylate methacrylate and / or monounsaturated alcohilo 5 to 68% of Acrylic acid and methacrylic acid and / or 2 to 15% of Acrylic and methacrylic acid and / or di - and trifunctional.The polymerization takes place by a radical mechanism, Mass under Ionizing Radiation. The Copolymer is Crushed and Separated fraction particle size of 20 to 50 microns. these materials have applications to produce drugs with delay.
