摘要
Tert. butyl gp.-contg. aromatic cpds., (I) are used as solvents in the radical-initiated copolymerisation of maleic anhydride with dicyclopentadiene or dicyclopentadiene-contg. olefin mixts., at 60-115 deg.C. The solvents can be recycled without purification. Residual solvent and excess maleic anhydride are easily removed. Copolymer swelling is very slight. The solvents are free from peroxide after polymerisation.
