Abstract

Los copolímeros de bloque de composición dual hechos de dieno conjugado y monómeros monovinílicos aromáticos en polimerización discontinua iniciada con organolitio muestran un rendimiento ventajoso en la producción de compuestos de caucho microcelular reticulado y adhesivos termofusibles sensibles a la presión. Los copolímeros de bloques de composición dual están parcialmente acoplados con un agente de acoplamiento que une bloques aromáticos monovinílicos internos. Su fracción de bajo peso molecular no acoplada tiene mayor contenido de unidades repetitivas monovinil aromáticas que su fracción de alto peso molecular acoplada. Los artículos de caucho microcelular reticulado hechos de los copolímeros de bloques de composición dual exhiben menor densidad, tamaño de celda más pequeño y más homogéneo, mayor suavidad y mayor elasticidad que los copolímeros de bloques de la técnica anterior. La formación de compuestos de caucho de formulaciones que comprenden los copolímeros de bloque de composición dual se produce a una torsión ligeramente más baja y a una temperatura ligeramente más baja que con los copolímeros de bloque de la técnica anterior. Los adhesivos termofusibles sensibles a la presión formulados con los copolímeros de bloque de composición dual son muy adecuados para etiquetas, exhibiendo una mayor pegajosidad y una temperatura de ablandamiento más alta que los hechos a partir de copolímeros de bloque de la técnica anterior.
