Degree of Unsaturation Dependence of Curing Reaction for Butyl Rubber Complexes

초록

Curing reaction for butyl rubber complexes applicable to a tire bladder is investigated as a function of the degree of unsaturation (DU). High molecular weight butyl rubbers with various DU were synthesized by cationic polymerization, providing three butyl rubbers between 1.8 and 8.4 mol% of DU. Dynamic mechanical measurement and swelling test were conducted for the systematic study of curing rate, curing density, aging, and curing mechanism. Our findings shed new light on technologically important butyl rubber-based materials.
