Abstract: Copolymers prepared by a reaction of (1) an unactivated olefin, (2) an activated olefin, and (3) a hydroxyl functional activated olefin and/or a hydroxyl functional unactivated olefin are described. The copolymers have a backbone of polar vinyl monomers and non-polar alkene monomers, with pendant hydroxyl functional groups. The copolymers are well suited for optically clear, pressure sensitive, polyurethane and/or barrier adhesives.

Abstract: Disclosed is a simplified process for formation of polyisobutylene functionalized with at least one terminal primary or secondary alcohol. The process comprises subjecting an olefin functional polyisobutylene, butyl rubber, or mixtures thereof to ozonation and reduction thereby forming mono-alcohol and diol functional polyisobutylene. The formed functional polyisobutylenes can serve as precursors for many other functionalized polyisobutylenes including urethane polyisobutylenes, urethane polyisobutylenes capped with (meth)acrylate functions, and (meth)acrylate capped polyisobutylenes.

Abstract: Disclosed are photoinitiators that are ultra violet (UV) reactive. The photoinitiators can be polymerized into polymeric backbones for use in UV curable hot melt pressure sensitive adhesives. The preferred polymeric backbones are acrylic-based polymers. The photoinitiators are very UVC sensitive and have excellent hot melt viscosity stability that is many fold higher than existing photoinitiators. The subject photoinitiators feature aryl ketones linked through an ether linkage to a variety of connector sequences that allow for polymerization of the photoinitiators.

Abstract: Provided herein are debondable adhesive compositions comprising (A) one or more bis-maleimide (BMI), nadimide or itaconimide oligomer(s), (B) at least one ethylenically unsaturated co-monomer (e.g. co-monomers selected from the group consisting of acrylates, methacrylates, vinyl ethers, vinyl esters, styrenic compounds, allyl compounds, polybutadienes, cinnamates, crotonates, and mixtures of any two or more thereof), and (C) a photoinitiator. In another embodiment, the present invention is directed to an assembly of a substrate and a carrier for the substrate in which the debondable adhesive composition temporarily bonds the substrates, and a method for fabricating the assembly. The debondable adhesive compositions maintain their adhesion at temperatures of 300° C. or greater, are easily and cleanly debondable at ambient conditions, permit temporary bonding at high processing conditions, and do not compromise handling or performance of the substrates.
