Abstract: The disclosure provides an associative polymer, a powder, a process for forming a paper sheet, and a process for making a powder. One or more associative polymers and one or more optional surfactants may be networked to form a wet gel and a powder may be formed from the wet gel. The associative polymer may have a weight average molecular weight of from about 10 kDa to about 2,000 kDa. A method may involve adding the powder to a cellulose fiber slurry, draining the cellulose fiber slurry to form a fiber pad, and drying the fiber pad to form a paper sheet.

Abstract: A perfluoro surfactant and a preparation method therefor. A carbon fluorine bond is not prone to break when the perfluoro surfactant is used as an emulsifier in a fluorine polymer reaction, such that the average molecular weight of a fluorine polymer generated in the fluorine polymer reaction is significantly increased. The preparation method is implemented in a continuous micro-channel reaction system, where the retention time of a reactant in the reaction system can be greatly shortened to few minutes or even seconds, a back-mixing phenomenon in the reaction system can be basically eliminated, and thus the occurrence of a side reaction, an optical coupling reaction, can be greatly reduced. There are reaction stages comprising an ozonization reaction and a photo-oxidation reaction.
