The photodegradation of the synthetic rubbers cis-1,4\_polybutadiene, polystyrenebutadiene and polyisoprene was studied. The chemical structure of the polymers as well as the effect of changing the solvent and the additive were particularly taken into consideration. The polychloroprene rubber in thi
cis-1,4-Polybutadiene (BR) samples, in the absence of crosslinking agents, were simultaneously compressed by ultrahigh pressures ( ΓΊ4.0 GPa) and annealed between 25 and 180ΠC. The BR samples were crosslinked when the annealing temperatures were above 100ΠC. The Vickers microhardness of the treated B
