  • Block-copolymer containing crosslinkable photoinitator groups
    Patent number: 9670295
    Abstract: A block-copolymer containing at least two different blocks wherein block A contains (meth)acrylate monomers the copolymer having a glass transition temperature of less than 15° C., block B contains (meth)acrylate monomers the copolymer having a glass transition temperature of more than 25° C. being free of thio-containing substances in the polymer chain, characterized in that one block contains at least one photoinitiator chemically bound to the chain.

  • CURABLE COMPOSITION COMPRISING CYANOACRYLATE MONOMERS
    Publication number: 20150075709
    Abstract: The present invention provides for curable compositions composed of one or more cyanoacrylate monomers, and one or more (co)polymers. The compositions of the present invention may exhibit pressure sensitive adhesion properties at 23° C. Subsequent cure of the compositions can be initiated as appropriate. For example, an external stimulus such as heat or radiation (e.g. UV cure) may be applied to induce cure of the composition when desired to do so.
