Abstract:
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.

Embodiments of the invention provide a class of mesophase separated ethylene/α-olefin block interpolymers with controlled block sequences. The ethylene/α-olefin interpolymers are characterized by an average block index, ABI, which is greater than zero and up to about 1.0 and a molecular weight distribution, Mw/Mn, greater than about 1.4. Preferably, the block index is from about 0.2 to about 1. In addition or alternatively, the block ethylene/α-olefin interpolymer is characterized by having at least one fraction obtained by Temperature Rising Elution Fractionation (‘TREF’), wherein the fraction has a block index greater than about 0.3 and up to about 1.0 and the ethylene/α-olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.4.
