The invention discloses a novel initiating system, and a preparation method and application thereof and belongs to the technical field of polymer compounds. The structure of an initiator is shown in the specifications, wherein R1, R2 and R3 are alkyl, phenyl or substituted alkyl and phenyl, and R4 is alkylidene. A compound (I) is prepared from acyl chloride and a compound containing a hydroxyl group. A method for preparing a compound (II) comprises the following steps of: reacting a reaction product of HOOCCH2R4CH2COOH and thionyl chloride and bromine to obtain a product; reacting the product and R3OH; and then reacting with R1COONa. The initiator is used for initating allyl monomers to be polymerized and has the advantages of safety in using and storage, simplicity in operation, simple synthesis method, and low cost, high-molecular weight polymer can be obtained; and a polymerization initiator system is expanded. |
