摘要： A specific class of water-borne, water redispersible laminating adhesives is disclosed which is desirable for bonding nonwoven substrates to themselves or to other substrates. The adhesives provide improved bond strength and improved water redispersibility when compared to laminating adhesives currently used for the same purpose. Furthermore, the novel adhesives are much less sensitive to the presence of significant levels of plasticizer than are laminating adhesives currently used, which exhibit reduced water redispersibility when such plasticizers are present in significant amounts. The novel laminating adhesives contain an aqueous styrene/acrylic polymer dispersion prepared by radical-initiated emulsion polymerization of unsaturated monomers in the presence of starch degradation products having a weight average molecular weight range of from about 2500 to 25000 and which are obtainable by hydrolysis in the aqueous phase. The adhesives may contain only the starch-modified, styrene/acrylic polymer dispersion, or may further include other components, such as plasticizers and/or rheology modifiers, when required. The novel adhesives are particularly useful in disposable articles wherein a nonwoven substrate is bonded to a second substrate via a water-borne, laminating adhesive. The disposable articles may include an absorbent core portion disposed between and proximate the nonwoven and second substrate.

摘要翻译：公开了一种特定类型的水性，水可再分散层压粘合剂，其将非织造基材粘合到其自身或其它基材上是理想的。与目前用于相同目的的层压粘合剂相比，粘合剂提供改善的粘结强度和改善的水再分散性。此外，与当前使用的层压粘合剂相比，新型粘合剂对于显着水平的增塑剂的存在不那么敏感，当这种增塑剂以显着量存在时，其表现出降低的水再分散性。新型层压粘合剂含有通过在具有约2500至25000的重均分子量范围的淀粉降解产物存在下由不饱和单体的自由基引发的乳液聚合制备的水性苯乙烯/丙烯酸聚合物分散体，其可通过在水相。当需要时，粘合剂可以仅含有淀粉改性的苯乙烯/丙烯酸聚合物分散体，或者可以进一步包括其它组分，例如增塑剂和/或流变改性剂。新型粘合剂在一次性制品中特别有用，其中非织造基底通过水性层压粘合剂结合到第二基底。一次性物品可以包括设置在非织造材料和第二基底之间和附近的吸收芯部分。

摘要： Hot melt adhesive compositions are prepared from 20 to 98% by weight of a polylactide homo- or copolymer containing at least 20 molar percent of the lactide component; 2 to 80% by weight of a polar tackifier having a Ring and Ball softening point (as described by ASTM E-26) greater than about 60.degree. C.; 0 to 50% by weight of a plasticizer; 0 to 30% by weight of a wax diluent; 0-3% by weight of a stabilizer; and 0-20% of a polymer. By utilizing a naturally occurring, thermoplastic, biodegradable copolymer as the base polymer, these adhesives advance the state of the art of hot melt adhesives by alleviating the dependence on petroleum based materials and by allowing for the development of hot melt adhesives which either degrade naturally after coming in contact with the soil or which can be composted.
