摘要:
Disclosed are hot-melt adhesive compositions comprising discrete particles of polyester adhesives, discrete particles of polyester containing a halogenated organic compound and discrete particles containing an antimony compound. Also disclosed is a method of incorporating both a halogenated organic compound and an antimony compound into a polyester adhesive composition.

Disclosed is an adhesive composition comprising:(a) an amorphous or a crystallizable polyester having a melting point of about 80.degree. C. to about 230.degree. C. and a heat of fusion of 0 to about 18 calories per gram, and(b) from about 1 to about 35% by weight of a compound selected from the group consisting of ##STR1## wherein R.sub.1 is benzyl or phenyl and R.sub.2 is benzyl, phenyl or an alkyl group containing 1 to 10 carbon atoms, and ##STR2## wherein R.sub.3 is phenyl or benzyl, R.sub.4 is phenyl or benzyl and R.sub.5 is an alkyl group containing 1 to 10 carbon atoms.
摘要:
Disclosed are plastisol compositions comprising a poly(vinyl chloride) resin, a plasticizer for the resin in an amount sufficient to form a plastisol, and from about 4 to about 20% by weight, based on the weight of the composition, of a saturated, thermoplastic polyester dispersed in the plastisol, the polyester being in particulate form, having a melting point of about 70.degree. to about 200.degree. C., a heat of fusion of about 10 calories per gram or less, and an inherent viscosity of about 0.3 to about 1.0.
摘要:
This invention is directed to blends of polymers of 2-substituted norbornenes such as poly(2-methoxycarbonyl-5-norbornene) and plasticized poly(vinyl chloride). These blends provide plasticized poly(vinyl chloride) compositions having high clarity as well as improved low temperature flexibility and improved low temperature impact strength.
摘要:
The hot-melt adhesives of the present invention comprise a blend of polyethylene, tackifier resin, and ethylene-alkyl acrylate or alkenyl carboxylate copolymers. These adhesive compositions have low melt viscosities, good flexibility at 20.degree. F., and provide good page pull and page flex values on books bound with these adhesives. Therefore, these adhesive compositions are useful as hot-melt adhesives for use in bookbinding applications.
摘要:
The hot melt adhesives of the present invention comprise a blend of polyethylene, amorphous polypropylene and crystalline propylene containing polymer. These hot-melt adhesive compositions have a novel combination of properties such as short hot tack times and open times for the bonding of paraffin-modified corrugated board.
摘要:
The hot-melt adhesives of the present invention comprise a blend of poly(propylene-co-higher 1-olefin), tackifying resin and crystalline propylene containing polymer. These hot-melt adhesive compositions have a novel combination of properties including strong T-peel and lap shear bonds to both low- and high-density polyethylene with excellent creep resistance at ambient temperatures. Therefore, these new hot-melt adhesives are excellent adhesives for applications such as sealing high-density polyethylene grocery bags and low-density shipping bags.
摘要:
The hot melt adhesives of the present invention comprise a blend of at least one polyethylene, a tackifying resin, and a Fischer-Tropsch hydrocarbon wax. This hot melt adhesive has a novel combination of properties which meet the requirements necessary for use in rapid bonding or closing applications.
