Summary
Basing on that the fluctuations of chains and junctions in real vulcanizates with carbon black fillers are suppressed by the presence of three kinds of forces which are network, entanglement and carbon black-polymer interaction forces. A new molecular theory of rubber elasticity for vulcanizates with carbon blacks at large deformation was presented. It succeeds in relating the elastic state to molecular constitution by three important quantities (C100, C020 and C200). In which the severity of constraints by entanglements, crosslink and junctions of carbon blacks are characterized with four molecular parameters.
,
,
and
. The relationships of stress to strain for four types of deformation were derived from this theory.
