    摘要: Processes for rendering a polyamine-epihalohydrin resin storage stable, including processes that prepare a storage stable resin and/or processes that treat resins. A composition containing a polyamine-epihalohydrin resin which includes CPD-forming species can be treated with at least one agent under conditions to at least one of inhibit, reduce and remove the CPD-forming species to obtain a reduced CPD-forming resin so that a composition containing the reduced CPD-forming polyamine-epihalohydrin resin when stored for 2 weeks at 50° C., and a pH of about 2.5 to 3.5 contains less than about 250 ppm dry basis of CPD. The invention is also directed to a gelation storage stable reduced CPD-forming resin so that a composition containing the reduced CPD-forming polyamine-epihalohydrin resin, when stored at pH 1 for 24 hours at 50° C. and measured at 24 hours, produces less than about 1000 ppm dry basis of CPD. A paper product containing the storage stable polyaminopolyamide-epihalohydrin resin, when corrected for adding at about a 1 wt % addition level of the polyaminopolyamide-epihalohydrin resin, contains less than about 250 ppb of CPD. Moreover, a resin can be prepared starting from a prepolymer having a low acid number or low concentration of acid end groups. The invention is also directed to papers containing the resins.

    摘要: Polyarylene polyethers, made by a process comprising reacting a dihydroxy compound and strong and weak bases in a liquid reaction medium at 100.degree.-200.degree. C. to form a double salt and then reacting the double salt with a slight molar excess of dihalobenzenoid compound bearing two replaceable halogens, are disclosed. The process reliably produces halogen-terminated polyarylene polyethers of select degrees of polymerization and desirable correspondence between weight and number average molecular weights. In subsequent steps amine-terminated polyarylene polyethers are made using the strong and weak bases. The resulting amine-terminated polyethers have a low, select degree of polymerization, desirable correspondence between weight and number average molecular weights and high level of amine termination.

    摘要: Stable aqueous dispersions of polyolefin fibers are formed by contacting the fibers with an aqueous solution of a cationic copolymer of an acrylamide and an acrylate or methacrylate ester, the pH of the aqueous solution having been adjusted to be in the range of from about 9.5 to about 12 either prior to, during or after contacting the fibers with said solution. An exemplary copolymer is that formed by the copolymerization of acrylamide and .beta.-methacryloyloxyethyltrimethylammonium methyl sulfate.
