## Abstract Der thermische Abbau von 1,2βPolybutadien vor und nach Gammabestrahlung wurde mittels GCβMSβKopplung untersucht. Depolymerisation unter Butadienabspaltung, die fΓΌr das unbestrahlte Polymere charakteristisch ist, tritt in bestrahlten Proben zurΓΌck. Weiterhin ist das VerhΓ€ltnis von Fragme

Mill behavior was examined with gum rubbers and carbon black-filled compounds of different types of cis-1,4-polybutadiene. The rubbers were Ti-, Nd-, and Copolymerized polymers. The Co-polymerized rubber contained crystalline particles of 1,2-polybutadiene. The carbon black was 50 phr N330. Photogra
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
