Abstract

"COPOLìMEROS DE MONOVINILARENO/DIENO CONJUGADO TENDO MENORES TEMPERATURAS DE TRANSIçãO AO VIDRO". Divulgamos um copolímero de bloco de monovinilareno/ dieno conjugado, compreendendo: (i) um bloco aleatório (de monovinilareno~ y~ /dieno~ x~ conjugado)~ m~, onde x é de cerca de 2,5% em peso a cerca de 10% em peso, y é de cerca de 90% em peso a cerca de 97,5% em peso, e x + y é de cerca de 97,5% em peso a 100% em peso; e (ii) um bloco (de dieno conjugado)~ n~; onde n é de cerca de 20% em peso a cerca de 30% em peso, m é de cerca de 70% em peso a cerca de 80% em peso, e m + n é de cerca de 90% em peso a 100% em peso. Também divulgamos um processo para formação do copolímero de bloco e um processo para fabricação de um artigo, a partir do copolímero de bloco. O copolímero de bloco exibe tipicamente uma T~ g~ pelo menos cerca de 10 <198>C inferior à T~ g~ de um polímero de referência, diferindo apenas em que x é cerca de 0% em peso e y é cerca de 100% em peso.
