    摘要： The invention relates to a process to modify polymers on-site the main process site.The process comprises on-site the main process site a receiving section (11 ) configured to receive an adduct solution as an interim polymer product for a process polymer of the main process site in solids contents of 15-60 wt-%, preferably 20-60 wt-%, more preferably 30-60 wt-%, a crosslinking section (13) configured to crosslink polymers of the adduct solution and a final section (14) configured to provide a ready-to-use solution with the crosslinked polymers to the main process as the process polymer on-site the main process site. The invention also relates to a method configured to modify polymers on-site at a main process site.

    摘要： The present disclosure generally relates to glyoxalated polyacrylamide (GPAM) compositions, methods of preparation and methods of use thereof, particularly in the paper industry. Moreover, the present disclosure generally pertains to cationic GPAM compositions, methods of preparation and methods of use thereof in papermaking applications and in products such as paper-based products, wherein the cationic GPAM compositions may provide increased wet and/or dry strength to the paper-based products, and wherein such cationic GPAM compositions optionally require a reduced volume of an aqueous carrier for storage or transport compared to a volume of an aqueous carrier needed for conventional GPAMs used in papermaking.

    摘要： Resins compositions and methods for making and using same. The resin composition can include a glyoxalated polyacrylamide resin and a polyamide-epihalohydrin resin. The polyamide-epihalohydrin resin can include a polyamine partially crosslinked with a bridging moiety and having azetidinium ions. The bridging moiety can be derived from a functionally symmetric crosslinker. A fiber product can include a plurality of fibers and the resin composition, where the resin composition can be at least partially cured.
