摘要

HOT-MELT ADHESIVES BASED ON VINYL POLYMER AND PROCESS FOR ADHERING SURFACES THEREWITH A hot-melt adhesive especially useful in the construction of disposable diapers contains a vinyl polymer of 40-90% by weight of a C1C12 alkyl acrylate and 10-60% by weight of an alpha-olefin of C20C40, wherein the alkyl acrylate may be partially replaced with vinyl acetate or with a C6-C12 olefin or with mixtures thereof, provided that the polymer contain at least 10% by weight of the alkyl acrylate. The adhesive may also contain a tackifying resin, a wax, an oil or a stabilizer depending on the specific end-use desired. In a preferred embodiment the polymer contains 20-45% by weight of the alpha-olefin.
