Tensile Strength Data from Electron Beam Cross-Linked Polybutadiene and Its Copolymers

Tensile Strength Data from Electron Beam Cross-Linked Polybutadiene and Its Copolymers 

Polymer Co-monomer, mol% Additive Amount of Additive(s), phr Dose, kGy Tensile Strength, MPa (psi) Reported 

Poly(butadiene-styrene) 22.5 N330 carbon black and 50 100 23.45 (3,400) 

Poly(butadiene-acrylonitrile) 32 Semireinforcing carbon black 50 100 22 (3,190) 

To this category belong homopolymers of polyisobutylene, copolymers of isobutylene and isoprene (butyl rubber), chlorobutyl, and bromobutyl. All these have been produced commercially for decades.
