WebHydrocarbon resins are amorphous thermoplastic polymers produced by polymerization of unsaturated hydrocarbons. The feedstock are various by-products of naphtha crackers. 1 These resins have typically a low molecular weight ranging from about 400 to 5000 g/mol. The three main types are C5 aliphatic, C9 aromatic, and DCPD cycloaliphatic resins. WebAddition polymerisation needs one type of monomer and forms one product.
