Abstract

The invention discloses a high compressive polystyrene-co-octadecyl methacrylate copolymer resin microsphere which is a crosslinking copolymer prepared by taking divinylbenzene as a cross-linking agent, taking styrene as a first monomer, taking octadecyl methacrylate as a second monomer and adding a pore-foaming agent. According to the high compressive polystyrene-co-octadecyl methacrylate copolymer resin microsphere, a long-chain flexible monomer of the octadecyl methacrylate is introduced to be copolymerized with the styrene, and therefore, the compressive strength of the resin microsphere as parents of ion exchange resin or adsorbent resin is obviously improved, the strength increase efficiency reaches more than a dozen times, and the resin microsphere cannot be crushed on account of structural defects per se in the use process.

Description

technical field [0001] The invention relates to the technical field of adsorption and separation functional polymers and their synthesis, in particular to a high-pressure-resistant polystyrene-co-octadecyl methacrylate copolymer resin microsphere and a preparation method thereof. Background technique [0002] The so-called high compressive performance of resin microspheres refers to the single-particle compressive strength of resin microspheres, and its mechanical properties can also be expressed by impact resistance or impact strength. Styrene series resin microspheres prepared with divinylbenzene as a crosslinking agent have a stable structure and can be used to prepare various ion exchange resins by using the reactivity of the benzene rings: strong acid can be obtained by sulfonating the benzene rings chelating resin can be prepared by reacting with hexamethylenetetramine after chloromethylation of benzene ring; carboxylic acid resin can also be obtained by oxidizing the ...
