Recycling compatible PSA label
A label which is attachable to object surfaces includes a pressure sensitive adhesive layer having a coat weight equal to or higher than 10 g/m.sup.2. The adhesive layer has a composition which is free of alkylphenol ethoxylate and has been selected to comprise emulsion polymerized, water-dispersible acrylate polymer and non-ionic copolymer based on polyethylene glycol and polypropylene glycol such that when the adhesive layer is subjected to paper recycling process conditions, the adhesive layer resists disintegration into small fragments.
High impact resistant poly(lactic acid) blends
The notched Izod impact toughness and tensile elongation of poly(lactic acid) (PLA)-homopolymers are increased by about 2 to about 4 times by blending therewith a PLA-copolymer having a difunctional flexible middle segment such as a polysiloxane or a polyether from about 0.6 wt. % to about 20 wt. %. The PLA-homopolymer-PLA-copolymer blend having a difunctional flexible polymer from about 0.5 wt. % to about 10 wt. % is thermally annealed to provide impact toughness of at least about 5 kJ/m.sup.2 and tensile elongation of greater than 12%. This exceptional improvement observed in the PLA blend is a synergistic effect of the addition of the difunctional flexible polymer of the copolymer and thermal annealing. The improvement observed in the mechanical properties with high PLA homopolymer content above about 90 to about 98 wt. % is unusual and results in an increased scope of molding and thermoforming applications. The annealed PLA-copolymers having a difunctional flexible middle segment have also been found to have improved notched Izod impact properties.
