Thermoplastic resins of relatively low molecular weight produced by the catalytic and thermal polymerization of coumarone and indene. The coumarone content present in these resins is often less than 10%. Other resin formers present may include styrene, vinyltoluenes, methylindenes, methylcoumarones, cyclopentadiene, dicyclopentadiene and their methyl homologs.
