Abstract: Embodiments of the present invention relate to article comprising a polymer comprising one or more C3 to C40 olefins, optionally one or more diolefins, and less than 5 mole % of ethylene having a Dot T-Peel of 1 Newton or more, a branching index (g?) of 0.95 or less measured at the Mz of the polymer; and an Mw of 100,000 or less. This invention further relates to a process to produce an olefin polymer comprising: 1) selecting a first catalyst component capable of producing a polymer having an Mw of 100,000 or less and a crystallinity of 20% or less; 2) selecting a second catalyst component capable of producing polymer having an Mw of 100,000 or less and a crystallinity of 40% or more; 3) contacting the catalyst components in the presence of one or more activators with one or more C3 to C40 olefins, in a reaction zone.

Abstract: A low melt viscosity hot melt pressure sensitive adhesive composition having enhanced tack properties is provided. The composition is based on an S-I-S block copolymer having polystyrene and polyisoprene block segments blended with a petroleum tackier resin which is the Friedel Crafts polymerization product of (i) a cracked petroleum feed containing C.sub.5 olefins and diolefins or a mixture of C.sub.5 and C.sub.6 olefins and dioelefins copolymerized with (ii) from about 5 to 15% by weight of a monovinyl aromatic monomer having 8 or 9 carbon atoms, e.g., styrene. The composition optionally also includes a polystyrene--polyisoprene diblock copolymer and a processing oil. The composition may be readily applied as solvent-free melt to various substrates using coating die technology because of its low melt viscosity at coating temperatures.

Abstract: A low melt viscosity, hot melt pressure sensitive adhesive composition having enhanced tack properties is provided. The composition is based on an S-I-S block copolymer having polystyrene and polyisoprene block segments blended with a petroleum tackifier resin which is a blend of a C.sub.5 -C.sub.9 aromatic modified aliphatic petroleum resin and a hydrogenated, alicyclic monomer containing hydrocarbon resin. The composition optionally also includes a polystyrene-polyisoprene diblock copolymer and a processing oil. The composition may be readily applied as solvent-free melt to various substrates using coating die technology because of its low melt viscosity at coating temperatures.
