    Abstract: A cyclic siloxane compound, composition, method, and an article including the siloxane, wherein the cyclic siloxane has the following Formula (I): wherein: each R1 and R2 is independently a (C1-C4)alkyl; each L1 and L2 is independently a single bond, an alkylene, or an alkylene bonded to a group selected from oxy, thio, carbonyl, —NH—, and combinations thereof; each R3 is independently a linear (C14-C100)alkyl; each R4 is independently a (C1-C30)alkyl, a (C2-C30)heteroalkyl having at least one oxygen, sulfur, or —NH— group, or a (C1-C30)alkyl substituted with a fluoro, thiol, isocyanato, cyanato, hydroxyl, glycidoxy, or epoxy group; with the proviso that L1, L2, and R4 are selected such that each Si atom is directly bonded to an alkylene or an alkyl; m is an integer of at least 2; n is an integer of 0 or above; m+n is an integer of at least 3; and the cyclic siloxane compound is a solid at 25° C.

    Abstract: The present disclosure provides an aqueous dispersion. The aqueous dispersion includes a) water; b) a surfactant having at least one ethylenically unsaturated group; and c) polyester particles dispersed in the water. The polyester particles include a water-insoluble polyester having a weight average molecular weight of 20 kiloDaltons or greater, and the polyester particles have an average diameter that is submicron in size. Further, the present disclosure provides a method of making the aqueous dispersion. The method includes a) dissolving a water-insoluble polyester in a water-immiscible solvent to form a polyester solution; b) combining the polyester solution with an aqueous solution including water and a surfactant; and c) removing at least a portion of the water-immiscible solvent to form the aqueous dispersion including polyester particles dispersed in the water. The present disclosure also provides a photopolymerizable composition including a) water; b) a surfactant; c) polyester particles dispersed in the water; d) a photoinitiator; e) at least one ethylenically unsaturated monomer dispersed in the water; and f) an optional polymerization inhibitor. The present disclosure also provides coatings and articles prepared from the aqueous dispersion or photopolymerizable composition.
