| titleOfInvention | Graft polymerization of guar and other polysaccharides by electron beam |
| abstract | 【Task】 A method of grafting a galactomannan-type polysaccharide polymer, preferably guar, to a functional group in the presence of an unsaturated monomer in which the functional group described is compressed by irradiation with a high energy electron beam. The method includes depolymerization of the graft polymer to a preselected low molecular weight. Preferred galactomannans for processing by this method are guar gum, guar spritz and hydroxypropyl guar. Also, in a preferred embodiment, guar gum is preferably depolymerized to a molecular weight of less than about 700,000 daltons, and most preferably depolymerized to a molecular weight of about 100,000 daltons to about 250,000 daltons. Most preferably, the depolymerized guar has a polydispersity of less than about 3.0 and is useful in enhancing oil production in oilfield fracturing. |
