权利人:NEWSOUTH INNOVATIONS PTY LTD
摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

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:Use of a weakly ionic acrylic polymer in the synthesis of precipitated calcium carbonate
发明人：GUILLOT MURIELLE; KENSICHER YVES
权利人:COATEX SAS
摘要:The invention consists of the use, in a process for manufacturing a mineral material including in particular a precipitated calcium carbonate, of a polymer constituted of at least one vinyl monomer chosen from acrylic acid, methacrylic acid, acrylamide, methacrylamide or a cationic monomer, or mixtures thereof, and of at least one nonionic monomer. The use of this polymer makes it possible to reduce the carbonation time of the PCC, without however impairing its crystallographic structure and its granulometric characteristics.

标 题 :Microwave-assisted synthesis of polyacrylic beads and the use thereof
发明人：TEHRANI ROUZBEH AFSARMANESH; ALIMOHAMMADI FARBOD
权利人:UNIV TEMPLE
摘要:A novel method of synthesizing polyacrylic beads, comprising the steps of suspending a monomer and a cross-linking agent in a solution, heating the solution in a microwave reactor, cooling the solution, and collecting the polyacrylic beads. The polyacrylic beads can be used in to remove solutes from various solutions, including blood, porcine blood, dialysate, serum, contaminated water, wastewater, and combinations thereof.

标 题 :Process for synthesis of crystalline 2-methacryloyloxyethyltrimethylammonium chloride
发明人：PATTERSON KENDALL W
权利人:HERCULES INC
摘要:A process for preparation of 2-methacryloyloxyethyltrimethylammonium chloride crystals in high yields from dimethylaminoethyl methacrylate and methyl chloride is provided. Reaction takes place in an organic reaction solvent. The product crystals formed are washed with a washing liquid which is a non-solvent for the product crystals but which is a solvent for the reaction solvent, reactants and impurities therein. The product crystals are 2-methacryloyloxyethyltrimethylammonium chloride monomers which can be polymerized or copolymerized with other vinyl monomers to prepare flocculants.
