ABSTRACT:
Use of vinyl acetate-ethylene copolymer emulsions as laminating adhesives for rug backing is disclosed. The copolymer emulsions are prepared by admixing vinyl acetate-ethylene copolymer, dispersant and thickening agent together, with or without the addition of filler. The vinyl acetate-ethylene copolymer can contain between about 20 and about 70 parts by weight of vinyl acetate and between about 30 and about 80 parts by weight of ethylene. The resulting vinyl acetate-ethylene copolymer emulsions have a glass transition temperature (T.sub.g) of between about -35.degree. C. and about -10.degree. C.
