Abstract
The sol–gel transition behaviour of ultra-high molecular weight polyethylene (UHMWPE) in decalin, paraffin oil and camphene has been investigated. UHMWPE solutions exhibit a thermo-reversible gelation, recognized in gels, which is due to crystallization. Viscosity results indicated that polymer molecules disentangled more easily when camphene was used as a solvent. This characteristic implies that camphene is a more desirable solvent for solution processing of UHMWPE. A higher recrystallization temperature, Tc, also occurred at a higher gelation temperature, Tgel. The gel melting temperature, Tm,gel, was also measured and its dependency on polymer concentration was investigated using the Eldridge–Ferry equation. The reciprocal of the absolute gel melting temperature was found to have a linear relationship with the logarithm of polymer concentration
