▎ 摘  要

NOVELTY - Strong acid cation exchange resin i.e. polystyrene-benzene sulfonic acid compound (I) is new. USE - (I) are useful in amphoteric homogeneous mixed bed (claimed). ADVANTAGE - (I) utilizes multi-channel spray method to improve yield of embedded skeleton of cross-linked polystyrene, shortens production period of chlorination reaction, increases output, and further reduces production cost; prevents mixed cation and anion resin from being re-stratified during the use process, effluent quality is good, and periodic water production is large so that manufacturing and operating costs are low, energy saving and consumption reduction. DETAILED DESCRIPTION - Strong acid cation exchange resin i.e. polystyrene-benzene sulfonic acid compound of formula (I) is new. P = cross-linked polystyrene embedded framework. An INDEPENDENT CLAIM is also included for preparation of (I).
