Novel determining technique for the entanglement degree of ultra-high molecular weight polyethylene

A novel method for characterising the degree of entanglement of molecular chains was established based on information obtained using differential scanning calorimetry (DSC). This technique is based on crystal morphology and establishes a correlation with the number of entanglements in rheology. In particular, this method can be implemented to characterise the entanglement of ultra-high-molecular-weight polyethylene molecular chains and was demonstrated to be successful in resolving the problem of obtaining the GN0 value in the testing process of low-molecular-weight polyethylene.
