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, each P 1Be connected with X respectively, n is 2 or larger integer;

    P 1That 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 Wherein, described polyolefin chain (A1) is in the presence of the coordination polymerization catalysts of 4-11 group transition metal compound in comprising periodictable, the polyolefinic residue that at least a above alkene (being total to) polymerization that is selected from ethene, propylene, 1-butylene, 1-hexene, the 1-octene is obtained;

    The described polyolefin chain (A2) that contains the polar polymer side chain comprises by the unit (C1) of following general formula (VIII) expression and the unit (C2) that is represented by following general formula (IX);

    Described polar polymer chain (A3) but monomer (D) by the polymerization addition polymerization but or the monomer of ring-opening polymerization (E) obtain;

    The described polar polymer chain (A4) that contains the polyolefine side chain obtains in the following way;

    the homopolymerization macromonomer, or two or more macromonomers of copolymerization, this macromonomer is selected from the polyolefine macromonomer (M1) that represented by following logical formula V, by the polyolefine macromonomer (M2) of following general formula (VI) expression with by the polyolefine macromonomer (M3) of following general formula (VII) expression;

    Perhaps, copolymerization is at least a to be selected from (M1), (M2) and macromonomer (M3) and at least a monomer (B), and each contains the organic compound of at least one carbon-to-carbon unsaturated bond in vain in this monomer (B) choosing;

    A plurality of P 1Can be same to each other or different to each other, but all P 1Be except the situation of 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;

    X comprises the linking group that is selected from least one group in ester group, amide group and the ether group, and this linking group comprises altogether less than 200 atoms,
