A microspherical ionomer having a crosslinked structure, a preparation method, an application and a preparation system. The ionomer contains the structural unit A represented by the formula (1), the structural unit B represented by the formula (2), and a crosslinked structure provided by a crosslinking agent, wherein each of M 1 and M 2 is independently selected from H, a metal cation and a linear, branched or cyclic C 1 -C 20 saturated alkyl group, R is H or a methyl group; and at least a part of the structural unit A in the ionomer is introduced with a metal cation. The ionomer exhibits an excellent effect on the nucleation of PET and is used as a nucleating agent for PET modification to obtain a corresponding PET composition. Continuously preparing a system and method for cross-linking maleate ionomer microspheres and cross-linking maleic acid ionomer microspheres to realize continuous production, washing and separation of ionomer microspheres, effectively stabilizing separation effect and avoiding The centrifuge is frequently opened and stopped. |
