Dicyclopentadiene → Dicyclopentadiene styrene

Participants

Reaction Conditions

Reaction Steps

An autoclave having an internal volume of 1 liter was charged with 228 g of xylene, and heated up to 260° C. in an atmosphere of a nitrogen gas. A mixture of 190 g of dicyclopentadiene and 190 g of styrene was added over 2 hours while being stirred. The reaction was further conducted at the same temperature for 4 hours. An unreacted monomer, a low polymer and the solvent were removed from the resulting polymer solution to obtain a dicyclopentadiene-styrene copolymer having a number-average molecular weight of 690, a softening temperature of 110° C., a bromine value of 62 g/100 g and an aromatic ring content of 46% by weight.
