Abstract
Oligomers with polydiene sequences and crosslinkable grafts are useful as coatings for protecting metal surfaces as well as inking buffers. The oligomers contain a polydiene sequence of 1-100 diene links, from 1 to 20 polar functional groups, and from 1-20 acrylic or methacrylic groups. The oligomers have the general formula: ##STR1##
