Patent number: 9200104Abstract: The application provides a method of producing a comb polymer comprising the steps of: (a) Providing: (i) a plurality of monomers which are linear, branched or star-shaped, substituted or non-substituted, and have an olefinically unsaturated moiety, the olefinically unsaturated moiety being capable of undergoing addition polymerisation; (ii) an initiator compound; the initiator compound comprising a homolytically cleavable bond. (iii) a catalyst capable of catalysing the polymerisation of the monomer; and (b) Causing the catalyst to catalyse, in combination with the initiator, the polymerisation of a plurality of the monomers to produce the comb polymer. Catalysts and polymers obtainable by the process are also provided. Preferably, the comb polymer is capable of binding proteins and may be produced from monomers which are alkoxy polyethers, such as poly(alkyleneglycol) or polytetrahydrofuran.Type: GrantFiled: April 5, 2013Date of Patent: December 1, 2015Assignee: Warwick Effect Polymers LimitedInventors: David M. Haddleton, Francois LeColley, Lei Tao, Giuseppe Mantovani, Adrian Carmichael, Adam Peter Jarvis, Andrew Gregory Steward

Publication number: 20130163087Abstract: The invention relates to a coated glass substrate, especially a glass substrate comprising an anti-reflective layer (AR) with improved opto-energetic performances and a good mechanical and chemical durability. The glass substrate according to the invention comprises a glass sheet provided with a porous AR layer comprising a majority of silicon oxide in the form of (i) a sol-gel type matrix and (ii) particles. Advantageously, the AR layer also comprises a quantity of aluminium oxide, expressed in the form of Al2O3, that is more than or equal to 2 weight per cent and less than or equal to 5 weight per cent. Said layer also comprises at least 55 weight per cent of particles and a maximum of 80 weight per cent of particles in relation to the total weight of silicon oxide.Type: ApplicationFiled: August 31, 2011Publication date: June 27, 2013Applicants: AGC Glass Europe, AGC Flat Glass North America, Inc., Asahi Glass CompanyInventors: Francois Lecolley, Jean-Francois Oudard

Publication number: 20110151222Abstract: The present invention is directed to anti-reflective coatings and methods of making the same. More specifically, the present invention is directed to porosity graded anti-reflective coatings that are made by methods that comprise preparing a liquid composition with specific amounts of tetraethyl orthosilicate, polyethylene glycol, hydrochloric acid, ethanol, butanol and water; applying the liquid composition onto a surface of a heated substrate; and heating the coated glass system to a temperature higher than that of the heated substrate.Type: ApplicationFiled: December 6, 2010Publication date: June 23, 2011Applicants: AGC FLAT GLASS NORTH AMERICA, INC., ASAHI GLASS CO., LTD., AGC GLASS EUROPE, S.A.Inventors: Jean-Francois OUDARD, François LECOLLEY
