Synthesis and Properties of Butyl Rubber Produced by Solution Polymerization
Butyl rubber was synthesis by solution process in hexane-chloromethane mixed solvent using ethylaluminium sesquichloride/water as initiating system The product has comparable properties with BK1675(solution process) and EXXON268（slurry process）in terms of molecular, molecular distribution, unsaturated degree as well as processing properties of Mooney viscosity, vulcanization, tensile properties. The solution method will open up a new way to produce butyl rubber in China.
