ABSTRACT:
A new modified elastomer having a phenolic hydroxyl group on the side chain, which is excellent in physical properties, crosslinkability, thermal stability, tackiness, adhesiveness and compatibility, is obtained by copolymerizing at least one monomer selected from the group consisting of conjugated dienes, and mono-ethylenically unsaturated monomers, or graft-copolymerizing an elastomer prepared by polymerizing at least one monomer defined above, with a phenolic monomer represented by the general formula, ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are individually an alkyl group or a hydrogen atom.
