Title:
HIGH SOFTENING POINT COPOLYMER, ITS MANUFACTURING METHOD AND ITS HYDROGENATED COMPOUND
Document Type and Number:
Japanese Patent JP2004026969
Kind Code:
A
Abstract:
To economically provide a hydrogenated copolymer preferably used for a hot melt adhesive or the like as an adhesiveness donating agent having a high softening point and a high softening point copolymer used for its raw material.
The high softening point copolymer is a copolymer obtained by heat-polymerizing cyclopentadiene and/or dicyclopentadiene and a vinyl-substituted aromatic compound wherein a solvent used in the heat polymerization is not less than 0.1 to less than 0.5 time of the total monomer mass and the softening point is in the range of 100 to 135 °C. The hydrogenated copolymer is obtained by hydrogenating the high softening point copolymer.
