  • Patent number: 10526426
    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.

  • Patent number: 10414845
    Abstract: 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.

  • Patent number: 10392543
    Abstract: 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.

  • Patent number: 10329369
    Abstract: 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.

  • Publication number: 20190169478
    Abstract: 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.

  • Patent number: 9587062
    Abstract: 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.
