Abstract: Radiation-crosslinkable elastomeric compositions containing: (a) an elastomeric polymer containing abstractable hydrogen atoms in an amount sufficient to enable the elastomeric polymer to undergo crosslinking in the presence of a suitable radiation-activatable crosslinking agent; and (b) a radiation-activatable crosslinking agent of formula (I) wherein X represents CH3-; phenyl; or substituted-phenyl; or substituted-phenyl with the proviso that any substituents on the substituted-phenyl do not interfere with the light-absorbing capacity of the radiation-activatable crosslinking agent and do not promote intramolecular hydrogen abstraction of the radiation activatable crosslinking agent; W represents -O-, -NH-, or -S-; Z represents an organic spacer selected from the group consisting of aliphatic, aromatic, aralkyl, heteroaromatic, and cycloaliphatic groups free of esters, amides, ketones, urethanes, and also free of ethers, thiols, allylic groups; and benylic groups with hydrogen atoms intramolecularly accessible to the carbonyl group(s) present in the radiation-activatable crosslinking agent; and n represents an integer of 2 or greater. Further disclosed are novel photocrosslinkers based upon 2,4,6-tri(4-benzoylphenoxy)-1,3,5-triazines.

Abstract: Non-tacky, base polymers are plasticized into pressure-sensitive adhesives and comprise: a) about 100 parts by weight of a base copolymer having a Tg greater than about 0 DEG C, wherein the base copolymer is formed from and comprises: (1) about 50 to 70% by weight of a high Tg comonomer component, wherein the homopolymer formed from the high Tg comonomer component has a Tg of at least about 20 DEG C; (2) optionally, up to about 20% by weight based on the total weight of the base copolymer of an acidic comonomer; and (3) about 30 to 50% by weight of one or more low Tg (meth)acrylate comonomer, wherein the Tg homopolymer of the low Tg comonomer is less than about 20 DEG C, and b) about 1 to about 100 parts based on the base copolymer of a non-reactive, non-volatile, non-acrylic-based plasticizing agent.

Abstract: Laminated articles of the present invention are prepared using at least substrate to be bonded, a polymeric film, and a non-volatile plasticizer for coating at least one surface of the substrate or polymeric film to be bonded. Upon absorption of the plasticizer into the polymeric film, a laminate article is formed. Preferred laminates are useful in optical applications and do not require elevated temperatures and non-atmospheric pressures for timely bonding. Kits comprising an amorphous polymeric film and a sufficient amount of a non-volatile plasticizer for forming a laminate comprising the amorphous polymeric film and a substrate are also useful for practicing the method of the invention.

Abstract: This invention relates generally to a process for radiation cross-linking polymers. A monochromatic radiation source (e.g. an excimer lamp or excimer laser) can be used to cross-link elastomers and thermoplastic polymers compounded with a radiation activatable cross-linking agent such as anthraquinone, substituted anthraquinone, acetophenones (of the multifunctional or copolymerizable type), benzophenones (of the multifunctional or copolymerizable type), or substituted triazine. The invention also relates to a radiation cross-linkable composition, especially those which combine polymerizable and nonpolymerizable radiation-activatable cross-linkers.

Abstract: A hot-melt adhesive composition comprises a blend of at least one acidic polymer and at least one basic polymer. At least one of the polymers is a hot-melt adhesive. Thermally reversible crosslinks are formed between each of the two polymers. These crosslinks impart cohesive strength to the applied adhesive, without sacrificing ease of processing.
