실험 절차

A solution of 20.0 g of m-, p-vinyltoluene (mainly para-), 20.0 g of isobutyl methacrylate, 10 g of n-dodecyl methacrylate, 0.25 g of benzoyl peroxide (100%), and 25.0 g of isododecane or ISOPAR G (trade name) was introduced in a reaction pressure tube of about 100 ml. Nitrogen was bubbled through for 5 min. The pressure tube was sealed and immersed in an oil-bath of 80° C. After a reaction time of 16 h the viscous bright solution was admixed with 0.25 g of benzoyl peroxide and the pressure tube was sealed again and heated to 80° C. After a total reaction time of 40 h a very viscous transparent solution was obtained. The polymerization was quantitative and the polymer solution was diluted with fresh isododecane to a total weight of 250 g.
