Pressure jumps in PC: different way of glass solidification

Popis výsledku v původním jazyce

Volume relaxation measurements were performed on polycarbonate used for production of compact in range of pressures up to 200 MPa. For tests piston-die pvT instrument was used. Two different way of material solidification were performed. In the first type of tests the molten material was cooled down to glassy state and then pressure was applied. The measurement of sample expansion followed realising of pressure (pressure down-jump) was then performed after some period of annealing. In the second measurements the PC was solidified by application of pressure and then cooled to experimental temperature. After annealing the pressure was realized. It was found that relaxation after pressure down-jump is dependent on the path of PC solidification determinedby the total amount of relaxation changes and relaxation time-scales. Further the second type of test is capable to simulate injection-molding process, which is combination of cooling of polymer melt simultaneously with applying of proces
