标 题:N-vinylformamidopropionates and process for their synthesis
发明人：CHEN NING; RENZ WALTER LOUIS; PINSCHMIDT JR ROBERT KRANTZ; CARROLL WILLIAM EAMON
权利人:AIR PROD & CHEM
摘要:A process is provided for the synthesis of N-vinylformamidopropionates by the reaction of NVF with acrylic and methacrylic acid esters in the presence of a metal hydride catalyst. This process allows for the improved production of mono-functional monomers and also for the synthesis of new multi-functional monomers which are useful as crosslinkers and chain extenders in photo-cure applications.

权利人:AVECIA BIOTECHNOLOGY INC
摘要:A process for the synthesis of an oligonucleotide is provided in which an oligonucleotide is assembled on a swellable solid support using the phosphoramidite approach in the presence of an activator, wherein the activator is not tetrazole or a substituted tetrazole. Preferred activators are pyridinium, imidazolinium and benzimidazolinium salts; benzotriazole and derivatives thereof; and saccharin or a saccharin derivative. Preferred swellable solid supports comprise functionalised polystyrene, partially hydrolysed polyvinylacetate or poly(acrylamide).

标 题 :Nanoliter-scale synthesis of arrayed biomaterials and screening thereof
发明人：ANDERSON DANIEL G; LEVENBERG SHULAMIT; LANGER ROBERT S
摘要:A method of screening cell-polymer interactions. The method includes depositing monomers as a plurality of discrete elements on a substrate, causing the deposited monomers to polymerize, thereby creating an array of discrete polymer elements on the substrate, incubating the substrate in a cell-containing culture medium, and characterizing a predetermined cell behavior on each polymer element.

标题 :Process for synthesis of telechelic urethane acrylate UV curable pre-polymeric materials
发明人：SYAMAKUMARI ASHA; PILLAI CHENNAKKATTU KRISHNA SADASIVAN
权利人:COUNCIL SCIENT IND RES
摘要:The present invention involves the design of a radiation curable organic pre polymer resin material based on urethane acrylic linkage synthesized from the natural renewable resource cardanol or a derivative thereof, for coating application. These new molecules have a faster and better curing rate compared to the starting renewable resource—cardanol. This is brought about by the hydrogen bonding of the urethane linkage which leads to a pre organization of the molecules in such a way as to bring the cross linkable double bonds closer to each other. The present invention also involves a UV curable formulation of the above mentioned resins along with 2-10 parts by weight of a photopolymerization initiator. The resin, either in a formulation or alone turns into a cross linked film upon photopolymerization in presence of photoinitiator under a UV curable radiation source like a mercury vapor pressure lamp.

标题 :Synthesis of superhydrophobic microporous surfaces via light-directed photopolymerization and phase separation
发明人：HOSEIN IAN D
权利人:HOSEIN IAN D; UNIV SYRACUSE
摘要:The formation of microporous surfaces through polymer induced phase separation in a photopolymer solvent mixture using photopolymerization via light self-focusing and self-trapping. The self-trapping of light sets fixed regions of brightness and darkness, sustained by the polymerization of light, and then wave guiding within the substrate. Phase separation occurs with the solvent phase separating in the regions of darkness and crosslinking in the regions of brightness. Upon removal of the solvent, precise and uniformly dispersed pores are created in the surface. The pore size and spacing may be tuned by adjusting the weight fraction of the photopolymer solvent mixture as well as through changes in the mask pattern.

标 题 :Synthesis of polythiol polymer intermediates from polyunsaturated hydrocarbons
发明人：OSWALD ALEXIS A; MUELLER WOLFGANG H; HALL DANIEL N
权利人:EXXON RESEARCH ENGINEERING CO
摘要:Polythiols having more than two terminal and/or pendant thiol groups per polymer molecule are formed by the free radical catalyzed addition of a monomer system made up of either hydrogen sulfide or a dithiol alone or in combination with an acetylenic compound to a polyolefin having at least three olefin sites. The polyolefin is preferably a tri-terminal olefin. The polythiol products are liquid, essentially gel-free materials having number average molecular weights varying from 200 to 30000. The polyfunctional prepolymers of the invention can be cured to stable three-dimensional networks with inexpensive bi-functional oxidants such as lead dioxide. Additionally, prepolymer compositions having 3 or more pendant or terminal thiol groups per molecule when combined with polyfunctional organic reagents, such as diepoxides, form stable, high-tenacity adhesive systems.
