Abstract
A resin comprising: (1) mainly a polybutadiene chain which is prepared from polybutadiene having a molecular weight of 500 to 200,000 and more than 30% of 1,2-configuration by hydrogenizing polybutadiene to the extent that at least about 30% of double bonds are contained in the polybutadiene molecule; (2) and olefinic bond group in the tip of the molecule; and, (3) a functional group selected from the group consisting of urethane, carboimino and ureylene which combine the polybutadiene chain and the olefinic bond.
