Harpikser af carbonhydrider af råolie (hydrogenerede) fremstilles ved katalytisk eller termisk polymerisation af diener og olefiner af alifatiske og/eller alicykliske typer og/eller monobenzenoidarylalken-typer fra destillater af krakket råolie med et kogepunktsinterval på højst 220 °C samt rene monomerer fundet i disse destillationsstrømme, efterfulgt af destillation, hydrogenering og supplerende forarbejdning.
Petroleum hydrocarbon resins, hydrogenated are produced by the catalytic or thermalpolymerisation of dienes and olefins of the aliphatic, alicyclic and/or monobenzenoidarylalkene types from distillates of cracked petroleum stocks with a boiling range not greater than 220 °C, as well as the pure monomers found in these distillation streams, subsequently followed by distillation, hydrogenation and additional processing.
