Further, a hydrogenated product obtained by substituting a carbon atom to which a group represented by the formula-(CH 2 ) n COOR 1 is bonded with a hydrocarbon group having 1 to 10 carbon atoms, particularly a methyl group, is obtained. It is preferable because it lowers hygroscopicity without lowering the softening temperature of the polymer.

The range is 0% by weight, more preferably 0 to 60% by weight.
