  • Patent number: 10358363
    Abstract: Novel fluorophores and their use as fluorescent tags for polymers used in wastewater treatment. The fluorophores are quaternary amine salts that can be used to synthesize fluorescent tagged polymers that are stable at varying pH, have significant water solubility, and may be fluorescent at wavelengths greater than 550 nm. The fluorophores readily undergo polymerization with vinylic monomers to form fluorescent tagged polymers with excellent incorporation of fluorophore into the polymer framework. The fluorescent tagged polymers are useful to monitor and optionally dose industrial wastewater.

  • Patent number: 8927637
    Abstract: A polymer, a composition, and uses for either are disclosed. The polymer is derived from at least two monomers: acrylic-x and an alkylamine, and has attached to the polymer backbone a functional group capable of scavenging at least one metal. The polymer has a polymer backbone with a fluorescing quantity of conjugated double bonds, thereby providing a method for controlling metal scavenging via fluorescence. These polymers have many uses in various media, including wastewater systems.

  • Patent number: 8444812
    Abstract: The invention provides a composition of matter used to produce very soft high grades of tissue paper. The composition of matter comprises a PAE resin acidified with a multifunctional acid. The multifunctional acid includes but is not limited to carboxyl and sulfonyl. The acid has a functional group selected from carboxyl and sulfonyl and a functional group selected from carboxyl, sulfonyl, hydroxyl, lactone, phenol, amine and heterocycle. The PAE resin facilitates the use of an adhesive in a Yankee Dryer apparatus that is durable when the adhesive is wet but remains soft when the adhesive becomes dry. These properties allow the adhesive to be strong and remain engaged to the dryer apparatus when wet but be easily removed by the creping blade when dry.

  • Patent number: 8101045
    Abstract: The invention provides a composition of matter useful for producing very soft high grades of tissue paper. The composition of matter comprises an adhesive composition that includes a glycerol-based polyol. The glycerol-based polyol prevents the composition from becoming brittle and is non-volatile. This allows the composition to become rewetted after creping and allows for strong levels of adhesion even at high temperatures.

  • Patent number: 5382323
    Abstract: Improved halogen-free Yankee Dryer adhesives based on cross linked cat ionic polyaminoamide polymers are described. The adhesives are obtained by crosslinking a backbone cationic polymer formed by reacting a difunctional carboxylic acid with a polyamine containing at least one secondary amine, said crosslinking achieved by the use of a multi-functional aidehyde. The preferred adhesive is that obtained by reacting adipic acid with diethylenetriamine, at essentially equimolar ratios of from about 1.2: 1.0 to about 1.0: 1.2, and then crosslinking with a dialdehyde selected from glutaraldehyde, glyoxal, or mixtures thereof. Improved adhesion and peel strength are obtained when using the new materials as compared to materials now commercially used.
