Document Type and Number:
WIPO Patent Application WO/2022/163395
Kind Code:
A1
Abstract:
Provided is a hydrocarbon resin which contains an aliphatic monomer unit or an aliphatic monomer unit and an aromatic monomer unit and which is characterized in that the number average molecular weight (Mn) falls within the range 400-3000, the weight average molecular weight (Mw) falls within the range 700-6000, the Z average molecular weight (Mz) falls within the range 1500-20,000, the ratio of the weight average molecular weight relative to the number average molecular weight (Mw/Mn) falls within the range 1.0-4.0, the ratio of the Z average molecular weight relative to the weight average molecular weight (Mz/Mw) falls within the range 1.0-4.0, the ratio of the peak top molecular weight relative to the weight average molecular weight (Mw) (peak top molecular weight/Mw) falls within the range of not less than 0.3 and less than 0.7, and the softening point temperature falls within the range 80-150ºC.
