Title:

PRODUCTION OF PARTIALLY HYDROGENATED PETROLEUM RESIN

Document Type and Number:

Japanese Patent JP2684494

Kind Code:

B2

Abstract:

PURPOSE: To efficiently produce the resin having a high tackifying capability by recycling a solvent alone without recycling a low-mol.-wt. polymer produced as a by-product during reaction.
CONSTITUTION: The resin is produced by polymerizing a cyclopentadiene compd. and a vinylarom. compd. in a solvent, separating and recovering a low-mol.-wt. polymer and the solvent from the polymn. mixture, and partially hydrogenating the remaining polymer to a degree of nuclear hydrogenation of 0-80%. The recovered solvent contg. no low-mol.-wt. polymer is reused as the solvent for the above polymn.
