    Abstract: A free-radically polymerizable crosslinker comprising divalent segments Z represented by the formula (I). Each divalent segment Z is respectively directly bonded to i) two secondary N atoms, each further directly bonded to a divalent segment Z or an X group; ii) two tertiary N atoms, each further directly bonded to p additional divalent segments Z and (2-p) X groups, wherein p is 0, 1, or 2; or iii) a secondary N atom further directly bonded to one additional divalent segment Z or an X group, and a tertiary N atom further directly bonded to p additional divalent segments Z and (2-p) X groups. R1 represents an alkylene group having from 1 to 4 carbon atoms, n represents a positive integer. X is represented by the formula: (II) L represents a covalent bond, O, S, NR1, or a divalent linking group having from 2 to 8 carbon atoms and up to 3 oxygen atoms. R2 is a free-radically polymerizable group selected from vinyloxy, allyloxy, methacryloxy, vinylaryl having from 8 to 12 carbon atoms, and 2-propenylaryl having from 9 to 13 carbon atoms. No two of O, S, or N atoms in the X group are adjacent. A curable composition comprises a monofunctional free-radically polymerizable monomer, a free-radical initiator, and the free-radically polymerizable crosslinker. At least partially cured reaction products are also disclosed.

    Abstract: The present disclosure provides a polymeric material including a reaction product of a polymerizable composition and having a solids content of 90% or greater. The polymerizable composition includes a uretdione-containing material including a reaction product of a diisocyanate reacted with itself, a first hydroxyl-containing compound having a single OH group, and a second hydroxyl-containing compound having more than one OH group. The first hydroxyl-containing compound is a primary alcohol or a secondary alcohol, plus the second hydroxyl-containing compound is a diol and the reaction product contains 0.2 to 0.5, inclusive, of diol equivalents relative to isocyanate equivalents. The present disclosure also provides a two-part composition, in which the polymeric material is included in the first part and the second part includes at least one amine. Further, a method of adhering two substrates is provided, including obtaining a two-part composition; combining at least a portion of the first part with at least a portion of the second part to form a mixture; disposing at least a portion of the mixture on a first substrate; and contacting a second substrate with the mixture disposed on the first substrate. The disclosure also provides a polymeric material and a method of making a two-part composition. Advantageously, two-part compositions according to the present disclosure can be used as coatings and adhesive systems with handling and performance similar to existing two-part urethane systems, but with less sensitivity to water.

    Abstract: A curable composition that includes a urethane multifunctional (meth)acrylate, an inorganic filler having a primary particle dimension of at least 200 nm, a photoinitiator system that can be activated by electromagnetic radiation in the range of 340-550 nm, a reactive diluent, and a reinforcing silica having a primary particle dimension of 100 nm of less. The sum of the absolute value of the difference in the refractive index of the filler and the refractive index of the composition cured without filler plus the birefringence of the filler is 0.054 or less, i.e. 0.054≥|nfiller−nmatrix|+δfiller, where nfiller is the refractive index of the filler, nmatrix is the refractive index of the composition cured without filler, and δfiller is the birefringence of the filler.

    Abstract: A polymerizable composition includes an organoborane-base complex that is a complex of an organoborane and a base, a decomplexing agent that at least partially liberates the organoborane from the organoborane-base complex, a polymerizable thiol-containing component comprising at least one polymerizable thiol-containing compound having a plurality of thiol groups in which the sulfur atom of the thiol group is covalently bonded to carbon, a hydroperoxide, and a polymerizable ethylenically-unsaturated component comprising at least one polymerizable ethylenically-unsaturated compound having a plurality of ethylenically-unsaturated groups. The combined amounts of the thiol-containing and ethylenically-unsaturated compounds total at least 50 percent by weight of all polymerizable material in the polymerizable composition. The composition may be provide as a two-part composition. Polymerized reaction product of the composition and methods of making the composition are also disclosed.
