Abstract: A surface treatment composition of the present invention comprises (A) urethaneacrylate oligomer, (B) acrylate based monomer, (C) photoinitiator, (D) silicon additive, and (E) silica matting agent. The present invention provides a surface treatment composition in which imparts abrasion and scratch resistance to the surface of a soft type urethaneacrylate oligomer decorative floor covering, and ameliorates the problem of low stain resistance caused a low density of elaborate crosslinks by using a small amount of single functional group monomer. The present invention also provides a surface treatment composition in which employs only hard type urethaneacrylate without single functional group monomer so that cross linking density is increased and the effects of oxygen that prohibits the surface curing are minimized, resulting in improved stain resistance.

Abstract: A method of making ionomeric particulate compositions by suspension polymerization are provided. The method comprises the steps of (a) forming an aqueous phase comprising an acid monomer, a metal oxide, and at least a first and a second surfactant, the first being a monomer surfactant; (b) forming an oil phase comprising at least one vinyl monomer; and (c) suspension polymerizing the aqueous phase with the oil phase to yield an ionomeric particulate composition.
