17 Claims

1. A method for manufacturing a hydrocarbon resin comprising at least one cyclic diolefin monomer component and at least one ethylenically unsaturated aromatic monomer component comprising

(a) heating to a temperature of at least 180° C. at a heating rate of 0.5 to 10° C./second a mixture comprising at least one cyclic diolefin monomer component and at least one ethylenically unsaturated aromatic monomer component having 8-13 carbon atoms, and

(b) polymerizing the mixture to form a hydrocarbon resin having a molecular weight of less than 2,500 g/mol, the molecular weight characterized as the centrifuge average (z-average) molecular weight,

wherein the mixture comprises a single phase liquid during heating and polymerization.
