DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) The title adhesives, derived from non-petroleum feedstock, comprise 320% of a polylactide homo- or copolymer contg. 320 mol.% of the lactide component, 2-80% of a polar tackifier having a ring-and-ball softening point >60°C, 0-50% plasticizer, 0-30% wax diluent, 0-3% stabilizer or antioxidant, and optionally ￡20% thermoplastic polymer, e.g., EVA, ethylene-Bu acrylate copolymer, etc. For example, a heat-resistant title adhesive with relatively high viscosity, useful for industrial bag applications, comprised a blend of poly(L-lactide), hydrogenated modified rosin (Hercolyn D) and terpene-phenolic resin (Nirez 300) tackifiers, and antioxidant (Irganox 1010). .
