摘要:Efficient condition optimization for the synthesis of highly branched polymers using high throughput screening has been developed. This innovation allows rapid production of soluble, highly branched polymers with different properties (molecular weight, degree of branching, etc.). Moreover, this versatile technique has the potential to be extended to other monomer/linker systems and polymerization techniques such as emulsion or suspension polymerization, anionic polymerization and continuous flow synthesis. A resin composition is further disclosed.

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).

摘要:The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH 3 —(CH 2 ) n —CH 2 OH, where n=22-24, are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the presence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than 85° C., and solidifying the acrylate. The methods may thereby provide safe and cost effective methods for curable wax production at large scale.

标题 :Process for synthesis of telechelic urethane acrylate UV curable pre-polymeric materials
发明人：SYAMAKUMARI ASHA; PILLAI CHENNAKKATTU KRISHNA SADASIVAN

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.

摘要:The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH3—(CH2)n—CH2OH, where n=22-24, and removing a fouled material in a reactor are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the absence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than about 85° C., solidifying the acrylate, removing the acrylate, and removing a fouled material in the reactor by emulsification.

权利人:US ARMY
摘要:A water-based and surfactant-free microwave synthesis of polymer nanoparticles includes the entrapment of diisopropyl fluorophosphatase (DFPase) within poly(4-vinylpyridine) (PVP) nanoparticles. The resulting nanoparticles are approximately 80-100 nm in diameter and reactive activity of DFPase is maintained after encapsulation.
