1. multi-branch polymer that comprises block structure, Grafting Structure or hub-and-spoke configuration, this polymkeric substance is represented by following general formula (I):

  • (P 1) n-X -----(I) Wherein n is 2 or bigger integer;

    P 1Be that number-average molecular weight is 500-1,000,000 polymer chain is selected from polyolefin chain (A1), contains polyolefin chain (A2), the polar polymer chain (A3) of polar polymer side chain and contains the polar polymer chain (A4) of polyolefine side chain;

    A plurality of P 1The condition that can be same to each other or different to each other is each P 1Not polar polymer chain (A3);

    When n is 2, at least one P 1It is the polar polymer chain (A4) that contains the polyolefine side chain;

    Be heteroatoms or contain heteroatomic linking group that with X this linking group comprises altogether less than 200 atoms.
