  • Publication number: 20110137004
    Abstract: A method of grafting galactomannan-type polysaccharide polymers, preferably guar, to a functional group by irradiation with high energy electron beams in the presence of an unsaturated monomer-compressing the described functional group. The method may include the depolymerization of the grafted polymer to a pre-selected low molecular weight. The preferred galactomannans for treatment according to this method are guar gum, guar splits and hydroxypropyl guar. In a preferred embodiment the guar gum is also depolymerized, preferably to a molecular weight of below about 700,00 Daltons, and most preferably to a molecular weight of between about 100,00 Daltons to about 250,00 Daltons. The depolymerized guar most preferably has a polydispersity of less than about 3.0 and is useful in oil well fracturing to enhance oil production.

  • Patent number: 7939601
    Abstract: The present invention relates to a polymeric material comprising units capable of having a cationic charge at a pH of from about 4 to about 12; provided that said polymeric material has an average cationic charge density from about 2.75 or less units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for hand dishwashing compositions and personal care products such as soaps, shaving cream foam, foaming shaving gel, foam dephiliatories and shampoos. The polymers are also effective as a soil release agent in fabric cleaning compositions. The polymers are also useful in agrochemical foam, fire-fighting foam, hard surface cleaner foam, and coagulant for titanium dioxide in paper making.
