Abstract
The invention provides aqueous coating composition having freeze thaw stability, comprising: (a) at least one latex polymer derived from at least one monomer and at least one reactive surfactant of the formula R1O—(CH2CHR2O)x—(CH2CH2O)y—(CH2CHR3O)z—R4 where R1 is either alkyl, aryl, alkylaryl, or aralkylaryl of 8-30 carbon atoms, R2 is —CH2OCH2CH═CH2 (AGE); R3 is either H, CH3, or CH2CH3; R4 is H or —SO3M or —PO3M where M is H or K, Na, NH4, NR4, alkanolamine, or other cationic species and x=2-100; y=4-200 and z=0-50.
