Title:
PRODUCTION OF HYDROGENATED POLYMER
Document Type and Number:
Japanese Patent JP3044586
Kind Code:
B2
Abstract:

PURPOSE: To obtain a hydrogenated polymer useful as a tackifier for adhesive, etc., having excellent thermal stability, tack, bond strength and retention power by polymerizing a mixture of a cyclopentadiene-based monomer and a specific norbornene-based compound and hydrogenating the polymer.
CONSTITUTION: (A) 0-90wt.% cyclopentadiene-based monomer is thermally polymerized with 10-100wt.%, preferably 20-100wt.%, more preferably 40-100wt.% norbornene-based compound of formula I [A and B are H or 1-10C hydrocarbon group; X and Y are H or monofunctional organic group and at least one of X and Y is H and polar group except hydrocarbon group, preferably group of formula II (R1 is 1-20C hydrocarbon group; (n) is preferably 0); (m) is 0-2] preferably in the absence of a radical initiator at 200-300°C and (B) the polymer is hydrogenated by using a catalyst (preferably palladium supported on a silica or magnesia carrier) under normal pressure to 300 atmospheric pressure in a hydrogen gas atmosphere at 0-300°C to produce the hydrogenated polymer.
