标 题:Synthesis of linear phosphorus-containing functional fluorocopolymer
发明人：WANG LIANG; WANG VIKTORIA
权利人:WANG LIANG; WANG VIKTORIA
摘要:This invention relates to a synthesis of a linear fluorocopolymer having a plurality of pendant phosphorus-containing functional groups. The synthesized phosphorus-containing fluorocopolymer has chain linearity and narrow molecular weight distributions. It has applications as a lubricant additive that provides friction-reduction, anti-wear, and corrosion protection properties.

标题:One step synthesis of ultrahigh molecular weight block copolymers
发明人：URBAN MAREK W
权利人:UNIV CLEMSON; UNIV CLEMSON RES FOUNDATION
摘要:Single-step synthesis processes for production of ultrahigh molecular weight block copolymers are described. The ultrahigh molecular weight copolymers can have a molecular weight of about 10 6 or greater and can be formed within a few hours in a surfactant-free environment. The formation process is controlled by initiator-starvation conditions in a sequential polymerization of monomers exhibiting different solubility in the solvent.

标 题:Manufacture of α-formylethanephosphonic acid esters
发明人：SCHREPFER HANS J; SIEGEL HARDO; THEOBALD HANS
权利人:BASF AG
摘要:α-Formylethane-phosphonic acid esters are manufactured by reacting vinylphosphonic acid esters with carbon monoxide and hydrogen in the presence of conventional rhodium-containing hydroformylation catalysts. The reaction is carried out at from 50° to 180° C. and at pressures from 20 to 1,500 bars. The products are intermediates for the synthesis of insecticidally active phosphoric acid ester derivatives.

标 题:Synthesis and use of grafted graphene in wellbore construction fluids for lubrication and corrosion inhibition
发明人：SANTRA ASHOK; THAEMLITZ CARL
权利人:ARAMCO SERVICES CO; SAUDI ARABIAN OIL CO
摘要:A composition of matter including a mono-facial polymer-grafted graphene particle and an aqueous-based drilling fluid is provided. In the composition, a first side of the graphene particle has a grafted polymer. A method of lubricating a tool surface using the composition of matter is also provided. The method includes providing an aqueous-based drilling fluid, the aqueous-based drilling fluid having a mono-facial polymer-grafted graphene particle, and introducing the aqueous-based drilling fluid into a wellbore such that it contacts a tool surface to form a coated tool. A drilling tool having a mono-facial polymer-grafted graphene particle adhered to its surface is also provided.
