An aqueous polymer emulsion comprising: i) as polymerized units, from 20% to 80% by dry weight, based on total dry weight of the polymer, of vinyl acetate; ii) as polymerized units, from 20% to 80% by dry weight, based on total dry weight of the polymer, of an a, ß-ethylenically unsaturated carboxylic ester monomer; iii) as polymerized units, from 0.1% to 5% by dry weight, based on total dry weight of the polymer, of a stabilizer monomer; iv) from 0.05% to 1% by dry weight, based on total dry weight of the polymer, of a surfactant, wherein said aqueous polymer emulsion has a viscosity of less than 100cps. An aqueous adhesive composition comprising said aqueous polymer emulsion. Una emulsión polimérica acuosa que comprende: i) como unidades polimerizadas, de 20 % a 80 % en peso seco, con base en el peso seco total del polímero, de acetato de vinilo; ii) como unidades polimerizadas, de 20 % a 80 % en peso seco, con base en el peso seco total del polímero, de un monómero de éster carboxílico a, ß-etilénicamente insaturado; iii) como unidades polimerizadas, de 0.1 % a 5 % en peso seco, con base en el peso seco total del polímero, de un monómero estabilizador; iv) de 0.05 % a 1 % en peso seco, con base en el peso seco total del polímero, de un tensioactivo, en donde la emulsión polimérica acuosa tiene una viscosidad menor que 100cps. Una composición adhesiva acuosa que comprende la emulsión polimérica acuosa.
