摘要
Abstract
Artificial joint is an important application of ultra-high molecular weight polyethylene(UHMWPE)with very high added value.The requirement on the molecular weight of UHMWPE for typeⅠ and Type Ⅱ artificial joints are at least 4.5×106 and 7.5×106,respectively.The accurate measurement of the molecular weight of such UHMWPE is important but not easy.This study discussed the theory of the viscometry method in the determination of molecular weight.It concluded that,on the one hand,the accurate molecular weight of UHMWPE could be obtained by the viscometry method under acceptable assumptions.It derived and verified the quantitative linear relationship of molecular weight and the melting point of UHMWPE from the polymerization of the Ziegler-Natta catalyst.关键词
