1. An anti-misting compound of formula (I): R((AO)nB)m((AO)nH)p, wherein
each AO group is, independently, an alkyleneoxy group selected from ethyleneoxy, 1,2-propyleneoxy, 1,2-butyleneoxy, and styryleneoxy groups; n is an integer from 2-to-15; m is from 1 to the total number of —OH hydrogens in the R group prior to alkoxylation; p is an integer such that the sum of m plus p equals the number of —OH hydrogens in the R group prior to alkoxylation; B is SO3Y, (CH2)qSO3Y, CH2CHOHCH2SO3Y, or CH2CH(CH3)OSO3Y, where q is an integer from 2-to-4, and Y is a cation; and R is compound selected from:
N(CH2CH2O)3 (V);(R2)xN(CH2CH2O)y (VI);where R2 is a C1-C4 alkyl, y is a number from 1-to-3, and x is a number such that x+y=3. |
