Chemical Stress Relaxation of cis-1, 4-polybutadiene

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1966
Polybutadiene is considered to be most promising elastomers in synthetic rubber industry as the result of remarkable improvement made on this material in recent years so that it contains now nearly all cis-1, 4 in its structure. The chemorheological study of this material is in this way becoming a very interesting subject.For the measurement of stress ...
