Patent number: 11505496Abstract: Embodiments of the invention relate to concrete admixtures, provide a phosphonato block polymer, a preparation method and an application. The method includes: the phosphonato block polymer prepared by copolycondensating an ether-type segment A, a phosphonato segment B, and a third part of aldehyde C. The ether-type segment A is obtained by polycondensating a polyether monomer and a first part of aldehyde C. The phosphonato segment B is obtained by polycondensating a monomer b containing phosphonato, a monomer c, and a second part of aldehyde C in an aprotic weak polar solvent E. By preparing a block polymer using arylalkane as a main chain and using a phosphonic acid or phosphinic acid functional group as an adsorption group, the invention improves the resistance of the block polymer to sulfate and clay interference, and can achieve initial high dispersion of concrete with a low water-cement ratio and decreasing of the system viscosity.Type: GrantFiled: February 22, 2017Date of Patent: November 22, 2022Assignees: SOBUTE NEW MATERIALS CO., LTD., BOTE NEW MATERIALS TAIZHOU CO., LTD.Inventors: Qianping Ran, Tao Wang, Jiaping Liu, Shuai Qi, Jianfeng Ma, Shimin Fan, Bing Wang, Zheng Han

Patent number: 8299206Abstract: Improved methods are described for solid-phase synthesis of morpholino oligomers, in which a protected morpholino ring nitrogen is deprotected between coupling steps using a heterocyclic amine salt in a trifluoroethanol-containing solvent, where the salt is a salt of a heterocyclic amine, having a pKa in the range of 1-4 in its protonated form, with an acid selected from a sulfonic acid, trifluoroacetic acid, and hydrochloric acid. Examples are 3-chloropyridinium methanesulfonate (CPM) and 4-cyanopyridinium trifluoroacetate (CYTFA).Type: GrantFiled: November 14, 2008Date of Patent: October 30, 2012Assignee: AVI BioPharma, Inc.Inventors: Christina Mary Josephine Fox, Dwight D.

Patent number: 8268959Abstract: This invention describes the synthesis and use of novel energetic poly(phosphazene) materials suitable for binding high explosives. These materials may also be used as explosives in their own right. The materials possess high energy density and are highly amenable to chemical modification thereby allowing for modification to the physical properties of the material. In particular the tacky and rubbery nature of these materials makes them ideal for use as binder and co-binder materials.Type: GrantFiled: September 21, 2005Date of Patent: September 18, 2012Assignee: The Secretary of State for DefenseInventors: Peter Golding, Stephen John Trussell, Martin Eamon Colclough, Javid Hamid
