Abstract

a presente invenção refere-se a uma composição de poliuretano termoplás-tico alifático que é bem adequada para uso em artigos de direcionamento de luz delgados e flexíveis, para conferir flexibilidade, tenacidade ou proteção aos artigos de direcionamento de luz que contêm elementos opticamente ativos. os poliureta-nos termoplásticos alifáticos revelados têm melhor estabilidade térmica em tempera-turas mais altas. especificamente, os poliuretanos termoplásticos alifáticos revela-dos têm uma temperatura de transição maior que 110°c. em uma modalidade, a temperatura de transição é maior que 130°c. em uma modalidade, a temperatura de transição é menor que 170°c, e tem uma tg superior a 35°c e inferior a 70°c.
