The compositions usually contain a filler, e.g. whiting, and may also contain an extending oil, e.g. naphthenic petroleum oil, and a thickening agent, e.g. polyacrylonitrile. Suitable latices include butadiene/styrene, carboxylated butadiene/styrene latices and mixtures of two such latices, polyisoprene, copolymer of butadiene with various monomers and natural rubber latex. In Examples, such adhesives are used to laminate a secondary jute backing to tufted carpets comprising nylon loop pile tufted to jute backing. The secondary backing layer may also be woven or non-woven textile or foam rubber.
