Stabilization of hot melt adhesives

A method of stabilizing a hot melt adhesive against degradation by one or more of light, oxygen and heat, the method comprising:

• adding a stabilizer composition to one or more hot melt adhesive materials selected from the group consisting of a polyolefin, a styrene-isoprene-styrene block co-polymer, a styrene-butadiene-styrene block co-polymer, a polyacrylate, a styrene-ethylene-butadiene-styrene acryl-copolymer, an ethylene vinyl acetate, a polyamide, a polyester, a polyurethane, a polyimide, a silane terminated polyolefin, a silane terminated polyether, and a silane terminated polyurethane,
• wherein the stabilizer composition comprises components (B) and (C),
• wherein (B) is a polymeric sterically hindered amine selected from the group consisting of:
• wherein n=5−8, and wherein (C) is sterically hindered phenol selected from the group consisting of:
