Abstract

BORRACHA SINTéTICA COM DISTRIBUIçãO DE PESO MOLECULAR LIMITADA, SEU USO E PROCESSO PARA SUA PREPARAçãO. A presente invenção refere-se a um processo novo que é usado para preparar borrachas sintéticas (B) que apresenta uma distribuição de peso molecular muito limitada e um valor correspondentemente baixo para o índice de polidispersidade. O processo de preparação abrange o tratamento de uma borracha sintética com ultra-som, onde a borracha sintética resultante (B) tem um peso molecular ponderal (Mw) menor do que a borracha sintética (A) usada. As borrachas sintéticas resultantes (B) têm excelente adequabilidade para processamentos através de processos de extrusor ou processos de moldagem por injeção.
