A hot melt adhesive composition that includes thermoplastic polyamide, adhesion promoter that includes at least one acid group, and wax having a melting point greater than 82&#xb0; C.

Polyamide adhesive and articles including the same

The present invention provides an article of manufacture having a coating or is otherwise surrounded in large measure by a second polymer which has non-blocking characteristics. In a preferred embodiment, the article possesses a core polymer which has a T of less than 25&deg; C. which is coated with or otherwise surrounded by a second polymer which has a T of greater than 25&deg; C., but less than 230&deg; C. Further, preferred core polymers have a number average molecular weight of about 3000 to about 100,000. A further feature of the articles of the present invention is that when heated to temperatures of about 100 to 300&deg; C., they undergo an ester exchange reaction to provide a substantially homogeneous polymer product useful in hot melt adhesive applications.

Non-blocking polymeric articles

The present invention is directed to an antiblock coating comprised of a composition that contains a dibenzoate ester moiety. The dibenzoate ester compounds, particularly 1,4-CHDM dibenzoate, provide an excellent non-stick coating to hot melt adhesives, thus providing for easier packaging, storage, and processing. In addition, such a coating facilitates recycling of materials to which the hot melt adhesive is.

Antiblock coating for hot melt adhesives

Provided are water-dispersible sulfopolyester compositions having relatively large proportions of pigments and/or fillers. Such compositions are useful as packaging materials and are substantially non-blocking when processed using packaging rolls and are comprised of at least one sulfopolyester as described herein, about 10 to about 75 weight percent of a pigment and/or filler, and a wax.

Water-dispersible films and fibers based on sulfopolyesters

Disclosed are linear, water-dispersible sulfopolyesters incorporating a low molecular weight polyethylene glycol and blocks of a high molecular weight polyethylene glycol. The block sulfopolyesters have improved toughness, abrasion resistance, flexibility, and adhesion. Particular utility is realized in polyester fiber sizing applications and as an adhesive.

Water-dispersible block copolyesters useful as low-odor adhesive raw

A yellow, hot melt alkyd traffic marking composition is described. The yellow, hot melt alkyd traffic marking composition contains 10-25 percent by weight of a hot melt alkyd binder, 5-10 percent by weight of a thermally stable 1,5- or 1,8-substituted anthraquinone colorant selected from a 1,5- or 1,8-substituted anthraquinone aromatic thioether and a 1,5- or 1,8-substituted anthraquinone aromatic thioether polyester, and 65-85 weight percent of a filler. The yellow, hot melt alkyd traffic marking composition of the invention may also contain other components used in traffic marking compositions, such as a reflectivity aid, a plasticizer, or an impact modifier. Other optional components are discussed below. The yellow, hot melt alkyd traffic marking compositions may be applied to any paved surface.

Yellow, hot melt alkyd traffic marking compositions

Disclosed is an essentially odorless water dissipatable or dispersible adhesive composition that is useful in forming paper articles and other products that can be recycled through repulping in both neutral and alkaline media. The water dispersible adhesive composition is preferably a hot melt adhesive that is a low molecular weight, branched copolyester containing a sulfomonomer. The copolyester adhesive composition can be used neat or formulated and exhibits broad compatibility with a variety of adhesive additives, including non polar tackifiers.

Water dispersible adhesive compositions

Disclosed is a water-dissipatable or dispersible adhesive composition that is useful in forming paper articles and other products that can be recycled through repulping in both neutral and alkaline media. The water-dispersible adhesive composition is preferably a hot melt adhesive that is a low molecular weight, branched copolyester containing a sulfomonomer. Additional utility for the invention resides in the manufacture of recyclable articles where insolubility in body fluids combined with solubility in tap water are required.

Water-dispersible adhesive blend composition and process

Disclosed is a radiation crosslinkable water-dispersible adhesive composition that is useful in forming paper and plastic articles and other products that can be recycled through a process which includes washing or repulping in aqueous media. The cross-linkable water-dispersible adhesive composition is preferably used as a hot melt adhesive. The cross-linkable water-dispersible adhesive composition is a low molecular weight, branched copolyester containing a sulfomonomer and unsaturated moieties. The radiation crosslinked adhesive composition has more cohesive strength and viscosity than its corresponding uncross-linked adhesive, yet is still water-dispersible during product recycling.
