摘要:
The present invention provides a hot melt adhesive which is excellent in high-speed coating and spiral coating at low temperature, and is also excellent in adhesion to a polyolefin film and a nonwoven fabric; and provides disposable products obtainable by using the hot melt adhesive. Disclosed is a hot melt adhesive including: (A) a thermoplastic block copolymer which is a copolymer of a vinyl-based aromatic hydrocarbon with a conjugated diene compound; (B) a propylene homopolymer having a melting point of 100°C or lower which is obtainable by polymerizing propylene using a metallocene catalyst; and (C) an ethylene/α-olefin copolymer. The hot melt adhesive is excellent in high-speed coating and spiral coating at low temperature, and is also excellent in adhesion to a polyolefin film and a nonwoven fabric.

Disclosed is a method for preparing polyolefin-based adhesives. In the method, a maleated polyolefin is blended, in sequence, with a polyolefin elastomer and then with a linear low density polyethylene. The polyolefin-based adhesive made according to the method of the invention shows improved clarity and adhesion in multilayer polyolefin films.

The invention relates to an adhesive composition comprising: —at least one hydrocarbon resin in an amount of at most 40% by weight with respect to the total weight of the composition; —at least one polyolefin derived from the polymerization of ethylene and/or propylene with metallocene catalysis having a density in the range from 0.8 to 0.9 g/cm3, and; —ethylene vinyl acetate (EVA) copolymer in an amount of at most 15% by weight with respect to the weight of the composition. Such adhesive composition allows preparing a ready-to-use adhesive product, applicable by rubbing and which does not require packaging during use.

An adhesive composition comprises: (i) at least one ethylene/α-olefin interpolymer, (ii) at least one tackifier; and (iii) an oil or a low molecular weight polymer. Preferably, the ethylene/α-olefin interpolymer has a Mw/Mn from about 1.7 to about 3.5, at least one melting point, Tm, in degrees Celsius, and a density, d, in grams/cubic centimeter, wherein the numerical values of Tm and d correspond to the relationship: Tm≧858.91−1825.3(d)+1112.8(d)2. The composition can be used in hot melt adhesives, pressure sensitive adhesives, hot melt pressure sensitive adhesives and thermoplastic marking paints.
