Acido-basic properties of a system containing a polymer obtained by decomposing by oxidative cleavage of a carbon-carbon double bond, and a trifunctional molecule having an alkoxysilyl group in the structure as represented by the formula (A) are changed such that the system is changed into a basic system when the system is acidic and the system is changed into an acidic system when the system is basic to combine the decomposed polymer and the trifunctional molecule, thereby introducing the alkoxysilyl group into the main chain. Furthermore, acido-basic properties of a system containing a polymer obtained by decomposing by oxidative cleavage of a carbon-carbon double bond to decrease the molecular weight, and a functional molecule having an alkoxysilyl group as represented by the formula (a) are changed in the same manner as above to combine the decomposed polymer and the functional molecule, thereby introducing the alkoxysilyl group in a molecular terminal. ##STR00001##

The invention relates to a novel synthesis method for forming superacid functional molecules that include monomers, as well as new polymers and copolymers formed from the monomers, and uses for these superacid molecules, polymers, and copolymers. The superacid molecules have an alpha, alpha-difluorosulfonic acid functionality that can be obtained by a reaction between various Grignard reagents and an alkyl(2-fluorosulfonyl)-1,1-difluoroacetate, such as methyl (2-fluorosulfonyl-1,1-difluoroacetate. The molecules, polymers and copolymers would be expected to have enhanced ion conductivity, and would be useful in a variety of applications, including as ion-conductive materials, surfactants, and ion exchange resins.

The present disclosure directs to the technical field of epoxy resins, and particularly relates to an antichlor and a preparation method as well as an application thereof, for solving problems in existing chlorine removal methods that separation efficiency of an epoxy resin containing hydrolyzable chlorine is low, lots of energy needs to be consumed in the separation process, molecular distillation equipment is expensive and requirements on vacuum degree and material tightness are high. The antichlor is a polymer containing keto-carbonyl groups. The preparation method includes: adding a mixed solution of styrene and ketene into a reactor containing an organic solvent; adding an initiator, a coupling agent and an anti-gelling agent into the reactor under an atmosphere of shielding gas; controlling the styrene and ketene to perform a polymerization reaction under first preset reaction conditions; and removing the organic solvent after completion of the polymerization reaction, thereby obtaining the antichlor.
