权利人:CALIFORNIA INST OF TECHN
摘要:The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are each independently an anionic ligand; n L is a neutral electron donor ligand; and, n R, R 1 R 6 , R 7 , R 8 , and R 9 are each independently hydrogen or a substituent selected from the group consisting of C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl.

权利人:UNIV CALIFORNIA; THE MITSUBISHI CHEMICAL CORP
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.

标题:Synthesis of amphiphilic block copolymers and polymeric nanofibers produced therefrom
发明人：ZETTERLUND PER B; ISHIZUKA FUMI; KIM HYUN JIN; CHATANI SHUNSUKE; NIINO HIROSHI
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.

摘要:The present disclosure relates to a process to produce a reinforced elastomeric material and to the reinforced elastomeric material. The process comprises the steps of providing components comprising a grafted elastomer, one or more dianhydrides, and one or more diamines; wherein the grafted elastomer is provided at a content of at least 60 wt.% based on the total weight of the components; performing in situ synthesis of a polyimide phase in the grafted elastomer by reactive extrusion of the components in a twin-screw extruder comprising main hopper wherein the screw profile comprises two or more reverse conveying elements forming two or more hot zones to form an elastomer-polyimide blend; and recovering said elastomer-polyimide blend being a reinforced elastomeric material.
