The spin-probe method was used to investigate the structure of composites prepared by blending of polyethylene with various contents of silica. When compared to original polyethylene, the temperature T50G was found to be lower at low filler content (

Hyperfine splitting constants of the nitroxyl radical, with and without hydrogen bonds to the surrounding molecules, have been calculated using the UHF method on a 6-31G * base. In polyethylene filled with silica, hydrogen bonds are formed between ni

The segmental size in amorphous poly(ethylene terephthalate) (PET) was determined by two methods: a) from deformational behavior of amorphous samples in the elastic state by optical birefringence measurement, and b) from dynamic behavior of a small s

The reactivity of 2(2-hydroxy-5-vinyl)2H-benzotriazole (2H5V) structural units in a copolymer with methyl methacrylate (MMA) with respect to alkyl or peroxy radicals in the solid phase was studied. Alkyl radicals were generated through mechanical deg

Analysis of the structure of nine polymers, in terms of the average size of free volume at T 50G for spin probe Tempo, reveals an empirical connection between this microstructural characteristic of matrices and the change in reorientational regime of

Changes in polyethylene (PE) when filled with Ultrasil have been studied by the method of positron annihilation. The results show that the temperature dependence τ3 is almost the same for all samples. Changes, however, occur in the intensities I3 an

Free radicals were generated in a rigid rod-like copolymer via mechanical route and by gamma radiation. The (EPR) method was used for studying free radicals formed at 123 K. The spectra of free radicals observed and the influence of molecular motions
