✦ Synopsis
A system similar to an interpenetrating polymer network (IPN), based on polyethylene/poly(methylmethacrylate-co-dodecyl methacrylate), was studied by the spin probe method with a nitroxide spin probe, 2,2,6,6-tetramethyl-1piperidinyloxy (TEMPO). The inÑuence of changes in the composition of the copolymer (methyl methacrylate-co-dodecyl methacrylate) on the molecular mobility and composition of the IPNs is characterized by changes of the empirical spectral parameters and The molecular mobility was shown to T 50G q R . diminish with rising content of methyl methacrylate in the copolymer.
