Abstract:
A hot melt adhesive composition, which may be used as a construction adhesive in hygiene articles, comprises a first polymer comprising a unimodal copolymer of propylene and ethylene and having a weight average molecular weight of between about 5,000 and 60,000 daltons; a second polymer comprising a copolymer of propylene and ethylene and having a weight average molecular weight of at least 100,000 daltons; a tackifying resin having a Ring & Ball softening point of at most 115° C.; and a plasticizer. The composition demonstrates good peel strength and good shear resistance and is sprayable, with a sufficiently low viscosity, at low application temperatures, such as at about 121° C.
