Abstract:

This invention relates to polymeric compositions that are processible and may be photochemically cured to produce crosslinked compositions useful in coating, sealants and adhesive applications. The crosslinkable composition comprises a first component having a plurality of pendent, free-radically polymerizable functional groups; a polymeric photoinitiator, and a residual content of less than 2%. The composition is melt processable at temperatures of less than or equal to 100Â C.

International Classification:

C09J13100

US Classification:

525193, 525205, 525206, 525218, 525221, 525222

Abstract:

Pressure sensitive adhesives are provided which possess high load bearing capabilities at elevated temperatures. The adhesives are prepared by polymerization of a syrup polymer composition having a first solute polymer having reactive, pendant functional groups, a second component having co-reactive functional groups, and a monomer mixture. The syrup polymer contains reactive electrophilic or nucleophilic functional groups that can subsequently crosslink by reaction with a second component having co-reactive functional groups.

Abstract:

The present invention provides novel compositions prepared from a first oligomer containing reactive functional groups capable of reaction at effective rates (at normal processing temperatures) with a co-reactive second component possessing functionality that is complementary to that of the first oligomer. The compositions may be used as coatings, including hard surface coatings, clear coatings, powder coatings and pattern coatings; as adhesives, including pressure sensitive adhesives and hot melt adhesives; as sealants; as optical coatings; as blown microfibers (BMF); as high refractive index optical materials; as barrier films; in microreplication; as low adhesion backsizes, (LABs) and as release coatings.
