Abstract

"POLìMEROS DE DIENO ALTAMENTE RAMIFICADOS". A presente invenção refere-se a polímeros altamente ramificados e acoplados à base de dienos conjugados ou de dienos conjugados e compostos vinilaromáticos, bem como de compostos orgânicos, polifuncionais com pelo menos quatro grupos capacitados para o acoplamento. A partir dos polímeros de dieno altamente ramificados de acordo com a invenção, podem ser produzidos vulcanizados ou artigos moldados de borracha de todos os tipos, especialmente pneumáticos, que apresentam uma melhor resistência ao rolamento.
