Abstract

EL INVENTO QUE PRESENTAMOS CONSISTE EN UN PROCEDIMIENTO PARA LA PRODUCCION DE LAMINAS O PLACAS DE POLIOLEFINAS DE MAYOR ESTABILIDAD: PARA ELLO, SE UTILIZA UNA MEZCLA DE ALEACION, FORMADA POR AL MENOS DOS POLIOLEFINAS, FISICA O QUIMICAMENTE DIFERENTES, O POR UN SISTEMA POLIMERICO FORMADO POR POLIMEROS, O POR BLOQUES POLIOFENICOS. EL PUNTO DE CRISTALIZACION DE LOS DISTINTOS COMPONENTES DEBE TENER UNA DIFERENDIA DE 5 A 80 GRADOS Y/O AL MENOS UNA POLIOLEFINA DEBE POSEEER UN VALOR DE VISCOSIDAD DE FUSION DE AL MENOS 190,5 MFI; ESTE VALOR DEBE SER DE 1,2 A 20 VECERS MAYOR QUE EL VALOR DE LA VISCOSIDAD DE FUSION DE LA OTRA POLIOLEFINA. LA ALEACION O MEZCLA DE POLIOLEFINAS SE ELABORA EN LAMINAS O PLACAS A UNA TEMPERATURA DE 3 A 40 C POR ENCIMA DEL PUNTO DE CRISTALIZACION DE LA POLIOLEFINA QUE TENGA EL PUNTO DE CRISTALIZACION MAS ALTO EN LA MEZCLA, ALEACION O SISTEMA DE POLIMEROS. EL DISPOSITIVO, EN FORMA DE LAMINA O DE TUBO, DONDE SE QUEDARA LA POLIOLEFINA O EL COMPONENETE DEL SISTEMA POLIMERICOQUE TENGA EL PUNTO MAS ALTO DE FUSION, ESTA SOMETIDO A UNA PRESION Y A UNA DISTENSION.
