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

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
