MANUFACTURE OF POLYPHOSPHAGEN MOLDED PRODUCT |
摘要 |
PURPOSE:To obtain a polyphosphagen molded product having favorable dynamic or mechanical properties industrially, by stretching the polyphosphagen molded product within a specific temperature range and heat treatment is applied to the same within a specific temperature range further. CONSTITUTION:A molded product having polyphosphagen (I) for its constituent component is composed of at least more than the 70wt% polyphosphagen to the whole polymeric component which is desirably more than 80wt%. The molded product is stretched at the temperature falling within a range shown by an expression of T(1)-30<=Td<=(1)+20 and then heat-treated at the temperature falling within a range shown by an expression of Td<Tn<=T(1)+100. In this expression the T(1) is the mesophase transition temperature ( deg.C) of a polyphosphagen molded product prior to stretching treatment, the Td is a stretching treatment temperature ( deg.C) and the Th is the heat treatment temperature. |
