ALTERNATIVE POLYETHYLENE CROSSLINKING CONCEPTS FOR POWER CABLE INSULATION
Doktorsavhandling, 2019
This thesis introduces alternative concepts for the crosslinking of polyethylene that fulfil these requirements. In particular, the suitability of click-chemistry epoxy ring opening reactions for curing of an ethylene-glycidyl methacrylate copolymer has been explored. Three main concepts for by-products free cable insulation have been studied: (i) crosslinking of LDPE copolymers with low molecular-weight multifunctional curing agents, (ii) Lewis acid assisted crosslinking of LDPE copolymer formulations, and (iii) reactive blending of LDPE copolymers. After extensive characterization of the thermo-mechanical properties of the materials, as well as preliminary conductivity studies, it can be anticipated that the concepts introduced in this thesis are a viable, by-product free and sustainable alternative to peroxide-based crosslinking of polyethylenes.
