ACTINICALLY-CROSSLINKABLE POLYSILOXANE-POLYGLYCEROL BLOCK COPOLYMERS AND METHODS OF MAKING AND USE THEREOF
Described herein are compositions comprising an actinically-crosslinkable polysiloxane-polyglycerol block copolymers, methods of making and use thereof, and devices comprising the compositions described herein. Disclosed herein are compositions comprising an actinically-crosslinkable polysiloxane-polyglycerol block copolymer derived from: a polysiloxane prepolymer comprising a polyglycerol side chain, the polyglycerol side chain comprising an ethylenically unsaturated group covalently linked thereto, wherein the ethylenically unsaturated group is actinically curable.
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.
