Abstract
"HIDROGEL POLIMéRICO PARA EMPREGO NA REPARAçãO DE DEFEITOS OSTEOCONDRAIS", caracterizado pelo fato de compreender hidrogéis de poli (2-hidróxi etil metacrilato), copolímeros de poli (2-hidróxi etil metacrilato-co-ácido acrílico) e blendas de poli (2-hidróxi etil metacrilato) com outros polímeros lineares das classes acrilatos ou metacrilatos, sendo que os hidrogéis de poli (2-hidróxi etil metacrilato) são sintetizados pela polimerização de uma mistura contendo 2-hidróxi etil metacrilato, um agente de reticulação que pode ser um di ou triacrilato tais como etileno dimetacrilato, etileno glicol dimetacrilato, trimetilol propano trimetacrilato, ou outro que se mostre adequado, em concentrações na faixa de 1 a 25% e um iniciador de polimerização."POLYMERIC HYDROGEL FOR USE IN THE REPAIR OF OSTEOCHONDRAL DEFECTS", characterized by the fact that it comprises poly (2-hydroxy ethyl methacrylate) hydrogels, copolymers of poly (2-hydroxy ethyl methacrylate-co-acrylic acid) and poly (2- hydroxy ethyl methacrylate) with other linear polymers of the acrylates or methacrylates classes, the hydrogels of poly (2-hydroxy ethyl methacrylate) being synthesized by the polymerization of a mixture containing 2-hydroxy ethyl methacrylate, a crosslinking agent that can be a di or triacrylate such as ethylene dimethacrylate, ethylene glycol dimethacrylate, trimethylol propane trimethacrylate, or other that is suitable, in concentrations in the range of 1 to 25% and a polymerization initiator.
