    摘要: A composition that includes polylactide resin and plasticizer, the plasticizer having a chemical formula: wherein R may be the same or different and wherein at least one R is a branched alkyl group having a carbon chain length of C5 or greater; and R is an H or an acyl group. In another aspect, the invention provides a process for providing an semicrystalline polylactide film, the process including the steps of providing a polylactide composition that includes polylactide resin, nucleating agent, and the foregoing plasticizer. The composition is extruded as a molten sheet which is then cooled to crystallize the polylactide and provide the film.

    摘要: The present invention provides an adhesive made from a reaction product of: (a) a polymerizable monomer derived at least in part from non-petroleum resources; (b) an initiator; (c) a polymeric stabilizer, wherein the reaction occurs in water to yield a microsphere adhesive. The microsphere adhesive can be formulated into a pressure sensitive adhesive composition that can be applied to various substrates such as paper and polymeric film to produce repositionable adhesive coated articles such as tapes, notes, flags, easels and the like.
