Patent number: 11028204Abstract: 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.Type: GrantFiled: July 7, 2016Date of Patent: June 8, 2021Assignee: Arkema FranceInventors: Sumeet Jain, William C. Wolf, Yuhong He, Jeffrey A. Klang

Patent number: 9695331Abstract: 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.Type: GrantFiled: April 9, 2013Date of Patent: July 4, 2017Assignee: Arkema FranceInventors: James P.
