Abstract: Hot melt adhesive compositions containing hyper-branched SBS block copolymers and end use applications thereof. The hyper-branched SBS is characterized in having a ratio between light-scattering molecular weight (of non-di-block polymer) and GPC molecular weight (of non-di-block polymer) greater than 1.4 and having ratio between light scattering molecular weight molecular weight (of non-di-block polymer) and light scattering molecular weight molecular weight (of di-block polymer) greater than 5. The ratio between light scattering molecular weight MW (of non-di-block polymer) and light scattering molecular weight MW (of di-block polymer) also defines the number of arms for the hyper branched structure. The weight average molecular weight of each arm of the hyper-branched SBS block copolymer is less than about 100,000.

Abstract: An autofeeding low application temperature hot melt application system comprises a hot melt tank, a compact integrated auto feed, and operates at temperatures of not more than 260° F.
