摘要（英）：

The invention provides a polysiloxane polymer and a preparation method thereof. The polysiloxane polymer is shown in formula (I). The preparation method of the polymer comprises the following step: carrying out ring-opening polymerization reaction on methyl hydrogen cyclosiloxane and methyl vinyl cyclosiloxane, or methyl hydrogen cyclosiloxane, methyl vinyl cyclosiloxane and monomer A in the presence of organic silicon blocking agent and cationic polymerization initiator, thus obtaining the polysiloxane polymer, wherein the monomer A is dimethyl cyclosiloxane, methyl phenyl cyclosiloxane or R'-substituted methyl hydrogen cyclosiloxane; R' is methyl, phenyl, CH2CH2Ph, CH2CH2CN, CH2CH2CO2CH3, CH2CH2CO2C4H9, CH2CH(CH3)CO2CH3 or CH2CH2OR''; and R'' is C1-20 alkyl, cycloalkyl, ether or alcohol.
