Abstract
PROCEDIMIENTO PARA LA PREPARACION DE POLIMEROS DE CLORURO DE VINILO. CONSISTE EN EFECTUAR LA POLIMERIZACION EN SUSPENSION EN PRESENCIA DE 0,005 A 0,5 PARTES EN PESO DE POLIACETATO DE VINILO) POR 100 PARTES EN PESO DE MONOMERO, ADEMAS DE CON UN AGENTE DE SUSPENSION PRIMARIO; EL GRADO DE SOLVOLISIS DEL POLI (ACETATO DE VINILO) EMPLEADO ES INFERIOR AL 1K POR 100 EN MOLES, MIENTRAS QUE SU GRADO DE POLIMERIZACION ES DE 100 A 10000. COMO AGENTE DE SUSPENSION PRIMARIO SE EMPLEAN POLI(ALCOHOL VINILICO) CON UN GRADO DE SOLVOLISIS ENTRE 70 Y 9 POR 100 EN MOLES, UNO O MAS DERIVADOS DE CELULOSA O SUS MEZCLAS, TALES COMO HIDROXIPROPIL-CELULOSA,METILHIDROXIPROPIL-CELULOSA, Y/O HIDROXIETIL-CELULOSA.
