Crosslinked hydrophilic resins and method of preparation.

摘要: The invention is a crosslinked carboxyl-containing hydrophilic resin by compound corresponding to formula (1): R1-(O(CH(R?3)CH(R3)O)?y-C(O)-R2)x wherein R1 independently in each occurrence C?2-10? straight- or branched-chain alkyl moiety; R?2? alkenyl R?3? hydrogen methyl; x 2 greater; where 2, y 3 8; and greater, 7. In another embodiment, the process for preparation of resins which comprises A) contacting one more ethylenically unsaturated carboxylic acids, acid anhydrides, optionally comonomers with crosslinking (1) an aqueous medium, presence free radical redox initiator catalyst system, under conditions such that prepared. Optionally, properties are enhanced heating exhibits centrifuge capacity 25 (g/g) absorption load g/g ratio 0.6 greater.
