Fiber optic connector containing a curable adhesive composition

Multilayered film and film based assembly which are environmentally-compatible, and which exhibit one or more desirable characteristics of polyvinyl chloride (PVC) film and film based assemblies, such as clarity, flexibility and toughness, but without the environmental and health hazards associated with PVC materials, are provided. Also provided is a method of preparing such film and film based assembly.

Thermoset adhesive having susceptor particles therein

Chlorine-free multilayered films

Medical device assemblies constructed from multilayered films

Multilayered tubing which exhibits one or more desirable characteristics of polyvinyl chloride (PVC) tubings, such as clarity, flexibility and toughness, but without the environmental and health hazards associated with PVC materials, is provided. Also provided is a method of preparing such tubing.

Flexible, chlorine free multilayered tubing

The present invention provides improved, flexible retroreflective articles based upon an optically clear, aliphatic polyurethane polymer. The aliphatic polymer has a plurality of hard chain segments of the formula

Retroreflective article

Bulk polymerization process for making radiation curable polyurethanes which comprises:

Extruder polymerization of polyurethanes

Antimicrobial 2-nitro-3-phenylbenzofurans wherein the benzo or the 3-phenyl portion of the molecule is bonded to an alkylene or an oxyalkylene group which is in turn bonded to a basic nitrogen atom or to the nitrogen atom of an (N-lower alkanoyl)amino group.

Aminoalkyl and aminoalkoxy derivatives of 2-nitro-3-phenylbenzofuran

Tetrazol-5-yl 2-nitro-3-phenylbenzofurans and antimicrobial use thereof

A medical article having a layered antithrombogenic surface is useful as a polymeric implant. The article comprises a polymeric substrate coated with chitosan to which is appended an antithrombotic agent. A process for rendering the surface of a polymer antithrombogenic is disclosed.

Antithrombogenic articles

Compounds wherein 2-nitrobenzofuran is substituted by one or two phenyl groups and certain other substituents which are active as antimicrobial agents, processes for their use and intermediates therefor.

Derivatives of 2-nitrobenzofuran

Compounds wherein 2-nitrobenzofuran is substituted by one or two phenyl groups and certain other substituents which are active as antimicrobial agents, a processes for their use and intermediates therefor.

Certain mono-bromo bis-phenyl benzofurans

Certain benzofuran benzene acetic acid type compounds

The maleic acid adduct of anthracene is used as a starting material for 11-amino-12-carboalkoxy-9,10-dihydro-9,10-ethanoanthracene, which through reaction with nitrous acid in a protic solvent provides an 11-substituted-12-carboalkoxy-10,11-dihydro-5,10-methano-5H-dibenzo[a,d]cy cloheptene which is then converted into the useful intermediate 12-carboxy-10,11-dihydro-5,10-methano-5H-dibenzo[a,d]cycloheptene.

9-10 Ethanoanthracene derivatives
