    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.
