Abstract
Recyclable hot melt adhesive compositions suitable for plastic bonding may be prepared from styrene-ethylene-butylene-styrene tri-block and/or styrene-ethylene-butylene di-block copolymers which are tackified with at least one hydrogenated resin based on alpha-methyl styrene, vinyl toluene, styrene, coumarone-indene, dicyclopentadiene or mixtures thereof, optionally containing small amounts of white mineral oil or similar diluent. In addition, the adhesive may or may not include minor amounts of the above-described pure monomer resins (specifically composed of styrene, alpha methyl styrene or vinyl toluene or mixtures thereof) in their non-hydrogenated form to serve as end block reinforcing resins.
