The sprayable olefin-based hot melt adhesive and absorbent articles comprising the adhesive are disclosed. The sprayable olefin-based hot melt adhesive is particularly suitable for spraying at low application temperatures. The sprayable low application temperature hot melt adhesives have high green strength, excellent bond strength and aging performance. Moreover, the sprayable low application temperature hot melt adhesives allows for thin bond lines without bleed-through and burn-through risks for heat-sensitive substrates.

Hot melt adhesive composition and use thereof

The invention relates to a low application temperature hot melt adhesive. More specifically, the low application temperature hot melt adhesive comprises olefin copolymers with an average Melt Index greater than 5 but less than about 35 g/10 minutes at 190&#xb0; C. The adhesive is particularly useful in the construction of nonwoven articles.

Low application temperature hot melt adhesive

A low application temperature rubber-based hot melt adhesive having properties particularly well suited for use in the construction of disposable articles has been invented. The adhesive comprises a styrene block copolymer and a type of wax in an amount effective to produce a viscosity at 120&#xb0; C. of below about 10,000 centipoises, a cube flow at 130&#xb0; F. (54&#xb0; C.) of less than about 300%, a DSC crystallization temperature of less than about 75&#xb0; C. and a storage modulus of less than about 1.0&#xd7;10dynes/cmat 10 rads/sec (25&#xb0; C.).

A hot melt adhesive composition comprising

Hot melt adhesives based on sulfonated polyesters

A nonwoven disposable article is constructed using adhesive compositions containing 1 to 25% of a surfactant, which causes the adhesive composition to exhibit a contact angle of 90.degree. or less and a reduction in surface tension of less than or equal to about 35-40 dynes/cm, giving improved wicking capabilities to the nonwoven.

Hot melt adhesive compositions with improved wicking properties

Hot melt adhesive compositions, particularly biodegradable hot melt adhesives are prepared from 10 to 90% by weight of a thermoplastic methylol polyester prepared from the reaction of at least one dicarboxylic acid with a diglycidyl ether, a diglycidyl ester or a combination thereof; 0 to 90% by weight of a compatible tackifier; 0 to 80% by weight of a compatible plasticizer; 0 to 50% by weight of a compatible wax diluent and 0 to 3% by weight of a stabilizer.

Hot melt adhesives based on hydroxy-functional polyesters

Hot melt adhesive compositions are prepared from a water sensitive or biodegradeable thermoplastic adhesive polymer using sucrose benzoate as a tackifier. More particularly, hot melt adhesive compositions are prepared from 10 to 90% by weight of a biodegradable or water sensitive thermoplastic polymer, 5 to 80% by weight sucrose benzoate, 0 to 80% by weight plasticizing diluent, 0 to 50% by weight wax and 0 to 3% by weight antioxidant.

Sucrose benzoate as a tackifier for water sensitive or biodegradable hot

A water sensitive hot melt adhesive composition comprising 5 to 80% by weight of a A-B-A linear or radial rubbery block copolymer, 10 to 50% by weight of a water soluble or water dispersible plasticizer; 0 to 85% by weight of a compatible tackifying resin; 0 to 35% by weight polar wax; and 0 to 3% by weight stabilizer.

Water-sensitive rubber-based hot melt adhesives

A hot melt adhesive composition comprising 5 to 50% by weight hydroxypropyl cellulose, 5 to 40% by weight plasticizer of which up to 85% may be a water insoluble plasticizer; 20 to 70% by weight tackifying resin; 0 to 40% by weight polar wax; 0 to 30% by weight compatible polymer; and, 0 to 3% by weight stabilizer.
