Abstract
SE DIVULGA UN PROCESO PARA MEJORAR LA TASA DE POLI MERIZACION DE ESTADO SOLIDO DE LOS POLIMEROS DE TE REFTALATO ETILENICO QUE COMPRENDE COPOLIMERIZACION DE ACIDO TEREFTALICO O TEREFTALATO DIMETILICO Y GLICOL ETILENICO CON 2 A 10 MOL% DE GIICOL DIETILE NICO Y 0,1 A 10 MOL% DE DIMETANOL CICLOHEXANICO PA RA FORMAR UN PREPOLIMERO FORMANDO PARTICULAS SOLI- DAS A PARTIR DEL PREPOLIMERO Y POLIMERIZANDO EN ES TADO SOLIDO LAS PARTICULAS A UNA TEMPERATURA DE TRANSICION VITREA Y LA DEL PUNTO DE FUSION DE DI- CHAS PARTICULAS HASTA ALCANZARSE UN VALOR DE V.I. PREVIAMENTE DETERMINADO.A PROCESS IS DISCLOSED TO IMPROVE THE RATE OF SOLID STATE POLYMERIZATION OF ETHYLENE REFTALATE TE POLYMERS WHICH INCLUDES COPOLYMERIZATION OF TEREFTALIC ACID OR TEREFTALATO DIMETILICO Y GOLI DIOL YOL % OF CYCLOHEXANIC DIMETHANOL TO FORM A PRE-POLYMER FORMING SOLID PARTICLES FROM THE PRE-POLYMER AND CULTIVATING IN PARTS TO A GLASS TRANSITION TEMPERATURE AND A PARTICULAR VIEW MULTIPLE POINT OF A VASCULAR HAZARD PREVIOUSLY DETERMINED.
