TETRAFLUOROETHYLENE/PERFLUORO (ALKYL VINYL ETHER) COPOLYMER AND METHOD FOR ITS PRODUCTION |
摘要 |
<p>A tetrafluoroethylene(TFE)/perfluoro (alkyl vinyl ether) (PVE) copolymer and a method for producing the copolymer, wherein the molar ratio of polymerized units based on TFE/polymerized units based on PVE is in the range of from 98.1/1.9 to 95.0/5.0, and its melt flow rate at 372° C. is from 35 to 60 g/10 min., and a weight-average molecular weight/a number-average molecular weight is from 1 to 1.7. The copolymer of TFE/PVE is excellent in the mechanical properties and the injection molding properties.</p> |
