A new amphiphilic polymer i.e., polyethylene glycol (PEG) grafted crystalline neoprene, which was used as compatibilizer to improve the compatibility of elastomer and waterabsorbent resin, has been investigated. The synthesis was based on the reaction between chlorine in neoprene and sodium salts of
## Abstract A series of waterβbased polyurethane dispersions were synthesized by the polyaddition of isophorone diisocyanate, poly(oxytetramethylene) glycol, and dimethylol propionic acid as prepolymers, which were endβcapped and crosslinked with 3βaminopropyl trimethoxysilane (APTMS) to produce si
