Dual-cure compositions for use in high temperature adhesive applications, and particularly for temporarily adhesively attaching one substrate to another substrate, are provided. These dual-cure adhesives are silicone-based compositions that can be B-staged by exposure UV radiation to provide initial green strength, followed by a C-stage cure to give adhesives that can survive high temperature processes above 200° C., especially above 300° C., yet easy to debond afterwards to allow separation of the top and bottom substrates.

Debondable compositions

Provided herein are metal conductive compositions with improved conductivity. The improved conductivity is attributable to the addition of a sintering agent and a polymer emulsion.

Polymer emulsion as binder for conductive composition

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.

Olefin-acrylate copolymers with pendant hydroxyl functionality and use thereof

This invention relates to photocurable electron deficient olefin-containing compositions, such as those containing certain 2-cyanoacrylates, 2-cyanopentadienoates, methylidene malonates, and vinylidine cyanide, and photolatent bases. When exposed to radiation in the electromagnetic spectrum, the compositions show a delay cure property.

Photocurable electron deficient olefin-containing compositions

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.

Photoinitiators that are polymeric or polymerizable for use in UV curable pressure sensitive adhesives

A method of preparing high molecular weight poly(meth)acrylate polymers having narrow polydispersity indices (PDIs) by coupling poly(meth)acrylate building block units which themselves have narrow PDIs. The building block units have halogenated terminations, which when reacted with selected coupling agents, from the high molecular weight poly(meth)acrylate polymers.

A metal truss assembly comprises a plurality of C-shape structural members including at least one chord member and two or more adjacent web members, each structural member having a base and two opposing flanges. The at least one C-shape chord member has flanges extending from each side of the base with one flange having cutouts to receive two C-shape web members with a part of said flange of said chord member in place between said cutouts. Each said C-shape web member is placed into one of the cutouts in said flange to intersect the at least one chord member with the bases of the two C-shape web members adjacent the base of the at least one chord member.

Truss assembly

Disclosed is a highly fluorinated silicone resin and a method for making the same. The silicone resin includes M, T, optionally D and optionally Q type monomers and is crosslinkable. The resin has a fluorine content of at least 55 weight percent and a very low refractive index of less than 1.4. The resin is formed in a one step process and requires use of very specific solvents. Preferably the resin includes a first T type monomer having a fluoroalkane group to provide the fluorine to the resin. Preferably the resin includes a second T type monomer having a (meth)acryloyl function to enable cross-linking. The resin forms an effective liquid optically clear adhesive. The resin can be further combined with highly fluorinated (meth)acrylate monomers or perfluoro polyethers to provide even lower refractive indexes and improved adhesive properties.

Reactive resins and formulations for low refractive index and low dielectric constant applications

The present invention relates to controlled radical polymerization processes for making branched-functionalized block polyacrylate polymers and compositions formed therefrom. In particular, such reaction products are formed by ensuring that the reaction products are substantially flowable and non-gelling, indicating that substantially no polymerization has occurred. The branched-functionalized block polyacrylates may be further functionalized and/or polymerized.

Process for making branched reactive block polymers

The present invention relates to one-component UV and thermal curable temporary adhesives for use in high temperature applications, and particularly to adhesives for the temporary attachment of one substrate to another substrate, the adhesives comprising (i) the partial hydrosilylation reaction product of the reaction between the vinyl groups on 1,3,5,7-tetravinyl-1,3,5,7-tetramethylcyclotetrasiloxane and the terminal Si&#x2014;H hydrogens on a silane or siloxane having terminal Si&#x2014;H hydrogens, and (ii) a photo and/or thermal radical cure initiator. Also encompassed are assemblies including such an adhesive and methods of using the adhesives.

The present invention relates to living radical polymerization processes, reaction products of such processes, and compositions containing such reaction products. More particularly, the invention relates to a living radical polymerization to produce branched polymers, in particular branched polyacrylates.

Process of controlled radical polymerization of branched polyacrylates

The present invention discloses polymers prepared from polar vinyl monomers and non-polar olefin monomers with the polymers having high olefin content and high weight average molecular weights as well as methods of preparing them. The inventive polymers possess interesting properties that make them particularly attractive in several industrial applications.

High molecular weight polymers having high olefin content

Disclosed is a method for formation of block copolymers using a Single Electron Transfer Living Radical Polymerization (SET-LRP) process. The process can be used to form di and tri-block copolymers from vinyl monomers. In one embodiment the SET-LRP process comprises initially forming a macroinitiator using SET-LRP to form a first block of a di or tri-block copolymer and then using SET-LRP to form additional blocks of the copolymer. The produced block copolymers have very narrow polydispersity indexes and controlled molecular weights. The process permits incorporation of photoinitiators in any of the block formation reactions. The method also includes purification processes that result in a block copolymer having very low color making it useful in a variety of applications. In one application block copolymers prepared according to the present process can be used in hot-melt adhesives.
