摘要： A method for preparing polymer includes the steps of enabling olefin and unsaturated carboxylate be subjected to a polymerization reaction in the presence of a catalyst to generate an olefin-unsaturated carboxylate polymer. The catalyst has a primary catalyst and optionally a cocatalyst. The primary catalyst has at least one complex represented by formula I, formula I′, or formula I″. By selecting a reacted unsaturated carboxylate monomer, catalysts, and a suitable polymerization process, a spherical and/or sphere-like polymer having good shape is directly prepared without subsequent processing steps such as granulation, and the obtained polymer product is not prone to fouling in a reactor and is convenient for transportation.
