Interpenetrating polymer networks (IPNs) based on polyethylene (PE) an
d poly(methacrylate)s were prepared by in situ polymerization. A co-co
ntinuous phase morphology was obtained. The use of dodecyl methacrylat
e produces good compatibility between PE and poly(methacrylate)s. The
degree of PE crosslinking in IPNs has been estimated by comparison of
the melting temperatures of PE crystallites in pure crosslinked PE wit
h those in IPNs.
