A branched olefin copolymer comprises a branched building block containing polar functional groups and formed by radical polymerization reaction or anion polymerization reaction. A branched olefin copolymer comprises a building block A of formula (1) and a building block B of formula (2). -CH 2-CH(R 1>)- (1) [Image] R 1>H or 1-18C linear or branched aliphatic hydrocarbon; R 2>linear or branched aliphatic or aromatic hydrocarbon; F : heteroatom or heteroatom-containing linking group; Z : polymer segment containing O, N, halo, or aryl and having a molecular weight distribution of 1.0-3.0; W : alcoholic hydroxyl, phenolic hydroxyl, carboxylic acid, carboxylate, acid anhydride, amino, epoxy, siloxy, or mercapto; n : 1-3; m : 0-2. When n is 2 or 3, Z may be the same or different to each other. When m is 2, W may be the same or different to each other. W may be bound to the same or different atom of R 2>to form a cyclic structure. An independent claim is also included for a process for producing the branched olefin copolymer by sequentially conducting a step of synthesizing a polar group-containing olefin copolymer Q containing functional group G, preferably hydroxyl, carboxylic acid, ester, amino, epoxy, silanol, or acid anhydride; a step of converting the functional group G into a group having an ability to initiate radical polymerization; and a step of installing a polymer segment Z in the building block B in the branched olefin copolymer by radical polymerization of a monomer comprising a carbon-carbon double bond-containing compound R containing oxygen, nitrogen, halo or aryl. |
