Patent ID: 7067603

Claim:
An adhesive composition or formulation comprising a poly-alpha olefin interpolymer having: (A) from 60 to 94 mol % of units derived from one alpha mono-olefin having from 3 to 6 carbon atoms; (B) from 6 to 40 mol % of units derived from one or more other mono-olefins having from 4 to 10 carbon atoms and at least one carbon atom more than (A); and (C) optionally from 0 to 10 mol % of units derived from another copolymerizable unsaturated hydrocarbon, different from components (A) and (B); wherein (i) the diad distribution of component (A) in the interpolymer as determined by 13 C NMR divided by the calculated Bernoullian diad distribution is less than 1.07; and (ii) the interpolymer has a melting behavior as determined by DSC such that T m (interpolymer) is less than 153−2.78×[C B+C ] for any given concentration of (B) and (C) components, where T m is the major melting peak of the interpolymer at a given content of components (B) and (C) in mole percent, and [C B+C ] is the mole percent of component (B) plus the mole percent of component (C).
