The double-modulation ESR spin-probe technique was employed to study slow-motional dynamics in amorphous polymer matrices of polybutadiene, polyisobutylene, poly(methyl methacrylate), and paraffin. It was shown that the low-lying excitation levels of

The glass transition of natural rubber (NR) in a mixture with polystyrene (PS) was investigated by global thermally stimulated depolarization current (t.s.d.c.) measurements and by the partial polarization technique. The experiments were carried out

With the addition of 20 phr of BR granulate grafted with ethyl acrylate by the redox or gamma irradiation method to polyacrylic rubber compound, the properties of the rubber worsened, but remained within the range of properties characteristic for the

The radiation induced crosslinking of a polymer can be greatly affected by its environment and morphology. This is examined for rubber of identical source, but irradiated as (1) nonpurified, (2) purified rubber and (3) as an emulsion where the rubber

By the redox method and by gamma irradiation, it was possible to graft ethyl acrylate on to granulate of waste rubber. The quantity of grafted monomer was larger when gamma irradiation was used. When combining ethyl acrylate with 5-methylene-2-norbor

The spin-labeled and spin-probed alternating copolymers of poly(phenylvinyl alkyl ethers) with various alkyl groups (Me, Et, sec-Bu) in the ether moiety were investigated by electron spin resonance (ESR). Measurements were taken in different solvents

Spin-lattice relaxation measurements of composite systems with different monomer-to polymer ratios are consistent with the phase diagram described previously. Relaxation curve of the system with monomer content higher than Mcr shows behaviour differe
