Abstract

"POLìMERO DE MEMóRIA DE FORMA OU MOLDE PARA LENTES OFTáLMICAS DE COMBINAçãO E MéTODOS DE FORMAçãO DE PRODUTOS OFTáLMICOS". Um molde de lente de contato de polímero de memória de forma é formado a partir de uma folha de um polímero de memória de forma em uma prensa, uma ferramenta ágil ou por uma ferramenta ágil formada por um gás inerte a uma temperatura na ou acima da temperatura de transição vítrea, o qual, mediante isso, é resfriado para abaixo da temperatura de transição vítrea e removido dali.
