Abstract
Ultra-drawing behaviour in the gel-like spherulite press method has been investigated using two kinds of gel-like spherulites formed from 1.0 and 2.0 wt% solutions of ultra-high-molecular-weight polyethylene. The influence of chain entanglement density in a solution on the increase in strength and modulus with ultra-drawing is discussed. An equation predicting the maximum draw ratio from the drawing stress of the predrawn specimens is presented. It is concluded that the influence on the ultra-drawing behaviour of the spherulite size and lack of chain connection between spherulites can be ignored in this processing method.
