    摘要: A process for preparing fluorochemical monoisocyanates comprises reacting at least one fluorochemical alcohol represented by the formula CnF2n+1SO2NCH3(CH2)mOH, wherein n=2 to 5, and m=2 to 4, with 4,4′-diphenylmethane diisocyanate (MDI) in a solvent in which the resulting fluorochemical monoisocyanate is not soluble; wherein the molar ratio of fluorochemical alcohol:MDI is from about 1:1 to about 1:2.5.

    摘要: An abrasive article is provided that includes at least one binder system formed from a polymeric additive and a thermosetting resin. The polymeric additive includes a polymeric backbone having substituents attached thereto, wherein the substituents include at least one urethane linked nitrogen bonded side chain having about 5 carbon atoms or more and a terminal methyl group and at least one oxygen linked water solubilizing group. An abrasive article that includes the binder system exhibits an increase of workpiece surface abraded in a Woodsanding Normal Force Test as compared to an abrasive article including a binder system formed from a composition containing substantially no polymeric additive.
