Abstract:
Non-ionizing high intensity predominantly continuum light radiation having a source intensity of at least about 350 watts per square centimeter steradian when integrated throughout the entire spectral range of said continuum light radiation is used as the energy source in photochemical reactions. A convenient source of this non-ionizing high intensity predominantly continuum light radiation is a swirl-flow plasma arc radiation apparatus. Among the photochemical reactions that can be carried out, at unexpectedly faster rates and at higher conversions, are photoreduction reactions, photocycloaddition reactions, oxetane formation reactions, halogen additions, halogen substitutions, photonitrosation reactions, photosulfoxidation reactions, bisulfite addition reactions, and many other photochemical addition and substitution reactions.
Abstract:
DINORBORNENE COMPOUNDS, MANY OF THEM NOVEL, HAVE BEEN FOUND TO FORM POLYMERS HAVING A LADDER STRUCTURE. THE DINORBORNENE COMPOUNDS AND DINORBORNENE POLYMERS WITH OTHER POLYMERS SUCH AS THE POLYOLEFINS, VINYL POLYMERS, ACRYLIC POLYMERS, POLYESTERS PPOLYAMIDES POLYEHERS, POLYUREAS, POLYURETHANES, NATURAL POLYMERS, ETC., ARE READILY CROSS-LINKED BY IRRADIATION.
Abstract:
VARIOUS COMBINATIONS OF CERTAIN ORGANIC CARBONYL PHOTOSENSITIZER COMPOUNDS AND CERTAIN ORGANIC AMINE ACTIVATORS EXERT AN UNEXPECTED BENEFICIAL EFFECT ON THE PHOTOPOLYMERIZATION OF CERTAIN POLYMERIZABLE MONOMERS OR OLIGOMERS AND COATIN COMPOSITIONS CONTAINING THE SAME. THE SUITABLE CARBONYL COMPOUNDS CONTAIN A KETONIC OXYGEN, FOR EXAMPLE ONE CAN USE ACETOPHENONE OR XANTHONE, AND THE AMINES CAN BE PRIMARY, SECONDARY OR TERTIARY AMINES, FOR EXAMPLE, ONE CAN USE BUTYLDIETHANOLAMINE, TRIETHANOLAMINE, DI-N-BUTYLAMINE OR MORPHOLINE.
WHEREIN R IS CYCLO-ALKENYL OR BICYCLO-ALKENYL CONTAINING 5 TO 8 CARBON ATOMS. THE COMPOUNDS HAVE UTILITY AS DURABLE PRESS ADDITIVIES FOR TEXTILE FABRICS.
Abstract:
RADIATION CURABLE POLYMERS HAVING THE VINYL -(5-NORBORNENE-2-YLMETHYL) CARBAMATE GROUP POLYMERIZED THEREIN ARE USEFUL FOR THE PRODUCTION OF CROSSLINKED COATINGS, FILMS, 2WIRE INSULATION AND FABRIC TREATMENT.
Abstract:
Provided as catalysts for the formation of cellular urethane polymers ranging from flexible to rigid foams, are beta-amino carbonyl compounds wherein carbonyl is present as an amido or carboxylic acid ester group and the beta-amino group is present as dialkylamino or an N-morpholino or N,N''-piperazino heterocyclic nucleus. Effective in the catalysis of the waterisocyanate reaction, these beta-amino amides and beta-amino esters are used with particular advantage in the manufacture of water-blown flexible foams, both molded and free-rise, including high-resilience and flame-retarded foam. The beta-amino carbonyl catalysts allow for the formation of foam products essentially free of the odor associated with amines such as Nethylmorpholine. In view of this highly desirable characteristic and their other beneficial properties, the catalysts of the invention are advantageously employed as direct replacements for N-ethylmorpholine in high-resilience and other foam formulations.
Abstract:
Polymers containing a norbornenyl group are readily crosslinked by irradiation to produce insoluble products. The crosslinked products are useful as coatings on wood, metal, etc., as selfsupporting films, wire insulation, for the treatment of fabrics to render them more durable and crease resistant, as well as in the many known areas in which synthetic polymers are employed such as the production of molded and extruded shaped articles.
