Abstract
A novel copolymer resin having excellent compatibility with rubber and plastics, stable to air, easily soluble in the hydrocarbon solvents and free of gel, said resin being obtained either (1) by copolymerizing one or more of the monomeric substances selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted compounds thereof and one or more of the substances selected from the hydroxystyrene derivatives, or (2) by copolymerizing one or more of the monomeric substances selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted compounds thereof, one or more of the substances selected from the codimers of cyclopentadiene and/or alkyl-substituted compounds thereof and chain conjugated diolefins having 4 to 5 carbon atoms, and one or more of the substances selected from the hydroxystyrene derivatives. There are also provided compositions comprising said resin and rubber or thermoplastic high-molecular weight substances.
