Title:
スチレンおよびジシクロペンタジエンのモノマーから作製された熱重合共重合体
Document Type and Number:
Japanese Patent JP3934053
Kind Code:
B2
Abstract:
A hydrocarbon resin is prepared by (1) thermally polymerizing a mixture consisting essentially of (a) about 5 % to 25 % by weight styrene or aliphatic or aromatic substituted styrene, and (b) about 95 % to 75 % by weight based on total monomer content of a cyclic diolefin component comprising at least about 50 % by weight diclyclopentadiene. A method of producing an aromatic-modified resin having a Mz of less than 2000 through the addition of about 5 % to 25 % by weight styrene in combination with about 95 % to about 75 % DCPD monomer at a rate to consume styrene monomer at the rate at which it is added. Hydrogenation of this resin produces light colored, thermally stable products that are useful as tackifiers in adhesives.
