1. the method for preparing branched polymer by conventional free radical polymerization, is characterized in that step is as follows:

  • 10~

    100 parts of olefin monomers of take are monomer, and wherein said olefin monomer is vinyl acetate;

    0.1~

    10 part of (methyl) acrylic ester monomer that contains sulfydryl is branched monomer, and 0~

    100 part of benzene or toluene are made solvent, under the initiator of radical polymerization exists, reacts 8~

    36 hours to obtain branched polymer at 50~

    120 ℃

    ;

    Wherein said radical initiator is Diisopropyl azodicarboxylate, dibenzoyl peroxide, K 2s 2o 8, Na 2s 2o 8, (NH 4) 2s 2o 8;

    Wherein said branched monomer is the own ester of methacrylic acid sulfydryl.
