<p>The invention provides a composition that exhibits good adhesion to polyamide material and other materials, comprising 60 to 99 weight percent of a copolyester elastomer, and 1 to 40 weight percent of a novolac resin, based on the total weight of the copolymer elastomer and the novolac resin only, wherein the composition comprises greater than 50 weight percent copolyester elastomer based on the total weight of the composition. The invention also concerns an article comprising at least two materials bonded together at one or more defined contact surfaces, a first one of the bonded materials comprising a copolyester elastomer and a novolac resin. Such bodies can be welded, injection molded, and extruded simultaneously or sequentially.</p> |
