Abstract
Provided is a polar group-containing multi-component olefin copolymer comprising: structural units (A) derived from ethylene or an α-olefin; structural units (B) having a carboxyl group or a structure which forms a carboxyl group by an elimination reaction due to heat or an acid; and structural units (C) derived from acrylic acid, which do not have a carboxyl group, and which do not cause an elimination reaction due to heat or an acid under the same conditions as those for the elimination reaction due to heat or an acid in which the structural units (B) form a carboxyl group.
