64 to 79 wt vinyl acetate 5 to 40 wt preferably from 20 to 30 wt ethylene and 0 5 to 10 wt preferably 1 to 6 nma based on the total weight of the polymer these emulsions can be prepared according to the teachings in u s pat no 3 380 851 which is hereby incorporated herein by reference low formaldehyde self crosslinking vinyl acetate ethylene nma polymers can be formulated in accordance with the teachings of u s pat no 4 449 978 which is hereby incorporated herein by reference in the 39 978 disclosure a 50 50 mixture of nma and acrylamide is used as the mechanism for producing low formaldehyde crosslinkable polymers for nonwoven products aqueous ethylene vinyl chloride evcl polymer emulsions for use in preparing nonwoven and textile products are well known and sold commercially these polymer emulsions are formed by emulsion polymerizing vinyl chloride and ethylene with acrylamide or a derivative such as n methylolacrylamide the evcl polymers typically have a tg from 0 to 50 u00b0 c and comprise about 55 to 95 wt preferably 60 to 90 wt vinyl chloride about 5 to 35 wt preferably 10 to 30 wt ethylene and from 0 1 to 10 wt preferably from 1 5 to 5 wt acrylamide and or n methylolacrylamide based on the total weight of polymer other monomers can be emulsion polymerized into the polymer generally in small amounts they include but are not limited to a c 1 to c 15 alkyl vinyl ester a c 1 to c 15 alkyl.
