Abstract
A porous polymer has a pore volume of 0.3 to 2.5 cm3/g and comprises a pore having a first pore diameter and a pore having a second pore diameter. A ratio of pore volume of the pore having a first pore diameter to pore volume of the pore having a second pore diameter is 1 to 10:1. The porous polymer is obtained by self-polymerization or copolymerization of at least one of the phosphorus ligands, and phosphorous content of the porous polymer is 1 to 5 mmol/g. The porous polymer-nickel catalyst made of the porous polymer has a significant increase in water resistance, which may reduce the consumption of phosphorus ligands, eliminating the steps of removing water from raw materials and reaction system water control, which greatly saves process equipment investment. When used in the preparation of adiponitrile from butadiene, it has high catalytic activity, high reaction selectivity, and high linearity.
