The starting material for the production of these resins comes from petroleum C5 streams, containing straight-chain and cyclic molecules, mono- and diolefins, but no aromatics. Composition of the feedstock is of great importance, and varies from source to source. Resins can be produced with a wide range of desirable properties, depending on raw material, addition of modifying monomers (monoolefins, terpenes, aromatics), and operating conditions.
