Abstract

"COMPOSIçãO DE COPOLìMEROS DE NBR CARBOXILADOS OU NãO E COPOLìMERO DE ETILENO VINIL ACETATO (EVA) E COMPOSIçãO VULCANIZáVEL DE COPOLìMEROS DE NBR CARBOXILADOS OU NãO E EVA" A presente invenção refere-se a uma composição de copolímero NBR carboxilado ou não e EVA. A invenção diz respeito também a uma composição de copolímero NBR carboxilado ou não pré-reticulado com EVA e elastómero termoplástico, em que o NBR é pré-reticulado pela adição à composição de um monómero reticulante com funcionalidade maior ou igual a 3, podendo este ser selecionado de divinil benzeno, trimetacrilato de trimetilol propano, dimetacrilato de etileno glicol e isocianurato de trialila. Estas composições são particularmente úteis quando misturados a borrachas termoplásticas para a indústria calçadista, brinquedos, coifas, gaxetas e quaisquer outros artigos feitos de borracha. A borracha feita de presente composição exibe propriedades mecânicas, químicas e de fosqueamento aperfeiçoadas, sem apresentarem manchas ou raias superficiais
