Abstract

UNA COMPOSICION DE RESINA DE POLIMERO AROMATICO MONOVINILIDENO, OPCIONALMENTE REFORZADO CON GOMA, QUE INCLUYE: A) UN POLIMERO DE MATRIZ OPCIONALMENTE REFORZADO CON GOMA; Y B) UNA CANTIDAD PLASTICIZANTE DE UN SOLIDO (A TEMPERATURA Y PRESION AMBIENTE), PESO MOLECULAR BAJO, UN POLIMERO DE LIMONENO O ALFAMETILESTIRENO Y, OPCIONALMENTE, OTRO MONOMERO AROMATICO DE VINILO COPOLIMERIZABLE, CON UN PESO MEDIO DE PESO MOLECULAR DE 1000 A 70000, UN CONTENIDO DE VOLATILES DE HASTA EL 30% Y UNA TEMPERATURA DE TRANSICION VITROSA DE AL MENOS APROXIMADAMENTE 25 GRADOS C. LA COMPOSICION TIENE SORPRENDENTEMENTE CARACTERISTICAS DE FLUJO MEJORADAS, Y EN CAMBIO NO SE REDUCE SUSTANCIALMENTE SU RESISTENCIA O RIGIDEZ. LA INVENCION TAMBIEN INCLUYE UN PROCESO PARA PRODUCIR UNA ESPUMA DE POLIMERO DE CELULA CERRADA DESDE LA COMPOSICION DE ESTA INVENCION, UNA FORMULACION DE POLIMERO AROMATICO DE MONOVINILIDENO ESPUMABLE O EXPANDIBLE QUE INCLUYE LA COMPOSICION DE LA INVENCION Y UN AGENTE DE SOPLADO, Y LA ESPUMA DE POLIMERO RESULTANTE. VENTAJOSAMENTE, LA ESPUMA DE LA INVENCION PUEDE SER PRODUCIDA UTILIZANDO SOLO CO{SUB,2} COMO AGENTE DE SOPLADO.
