    Abstract: A multi(meth)acrylate-functionalized oligomer has a polyurethane backbone, a plurality of (meth)acrylate groups pendant to the polyurethane backbone, and one or more terminal (meth)acrylate groups. The oligomer contains a) at least one multi(meth)acrylate-functionalized segment having at least two pendant (meth)acrylate groups, b) urethane-containing segments, c) at least one end-cap segment having at least one (meth)acrylate group, and, optionally, d) a chain-extending segment (such as a non-polymeric aliphatic segment, polyether-containing segment, polyester-containing segment, polydiene-containing segment, polycarbonate-containing segment or polyorganosiloxane-containing segment). At least one multi(meth)acrylate-functionalized segment is located at a pendant position and at least one (meth)acrylate group is present at one or more terminal positions of the oligomer.

  • Patent number: 11028204
    Abstract: Curable compositions include: a) at least one (meth)acrylate monomer or oligomer and b) at least one mono-functional (meth)acrylate monomer comprising a polycyclic moiety having at least three rings that are fused or condensed. The compositions may comprise an initiator system to render the compositions as curable. The compositions may comprise both the a) and b) components in an amount from about 30% to about 70% by weight. The compositions described herein are advantageous with respect to properties such as viscosity, toughness, tensile strength and tensile elongation. Due to their advantageous properties, the compositions are viable for a wide range of applications including coatings, adhesives, sealants, inks and stereolithography. The compositions are liquid at ambient temperature and impart a high glass transition temperature, Tg, without sacrificing other properties, such as elongation. The compositions are useful in 3D printing.

  • Patent number: 9695331
    Abstract: The present invention includes silicon-containing (meth)acrylate compounds of formula (I): where A is a C1-C12 organic moiety such as an alkyl or aryl moiety, B is a silane functional group, C is a (meth)acrylate functional group and D is an allyl functional group, with w=0 or 1, z=0, 1 or 2, x=1, 2 or 3, y=1, 2 or 3 and w+x+y+z=4. The compounds are suitable for use in curable compositions, such as peroxide-curable compositions or radiation-curable compositions and may be applied to a substrate as a coating or sealant, for example. Compositions containing the silicon-containing (meth)acrylate compounds may have reduced volatility and odor problems along with improved adhesion to substrates, increased crosslink density and/or improved hardness.
