Abstract
The copolymerization of ethylene (E) and methoxy polyethylene glycol methacrylate (MPEGMA) produces the copolymer co-E-MPEGMA. These copolymers are distinct from polyethylene, e.g., low density polyethylene (LDPE) grafted with MPEGMA, i.e., g-E-MPEGMA, and are useful in the preparation of insulation sheaths for medium, high and extra-high voltage cables. Such cables exhibit good water tree retardance.
