Abstract

COMPOSICIONES ADHESIVAS CONTENIENDO UN COPOLIMERO DE TRES BRAZOS RADIALES HIDROXI-FUNCIONALIZADO, CUYOS BRAZOS CONTIENEN BLOQUES DE ESTIRENO-ISOPRENO, EN LOS QUE EL PESO MOLECULAR MEDIO DE LOS BLOQUES DE POLIESTIRENO ES INFERIOR A 30.000 Y, GENERALMENTE, ESTA COMPRENDIDO ENTRE 7.000 A 30.000, Y EL PESO MOLECULAR MEDIO TOTAL DE LOS CITADOS POLIMEROS EN BLOQUE ESTA COMPRENDIDO ENTRE 120.000 Y 250.000. TAL COPOLIMERO RADIAL FUNCIONALIZADO HACE POSIBLE, DE CONFORMIDAD CON LA COMPOSICION MONOMERICA ADOPTADA, Y MEDIANTE MEZCLA ADECUADA CON RESINAS PEGAJOSAS Y ACEITES PLASTIFICANTES, LA OBTENCION DE COMPOSICIONES ADHESIVAS, QUE PUEDEN SER DEL TIPO "FUSION EN CALIENTE", O DEL TIPO QUE LLEVA DISOLVENTE, PRESENTANDO BUENAS PROPIEDADES ADHESIVAS Y COHESIVAS, TALES COMO ASEGURAR UN EQUILIBRO OPTIMO ENTRE ESTAS PROPIEDADES Y SU FACULTAD DE PROCESAMIENTO.
