  The invention described herein provides a novel lactide monomer derivative and process for preparing the lactide monomer derivative. The monomer derivative of the invention is bifunctional in nature, and can be employed a variety of efficient synthesis processes to prepare various polymers. Further, the bifunctional monomer derivative can be used to prepare various intermediate-stage compounds and polymers, which in turn can be used to synthesize other compounds, polymers, copolymers and composites. The lactide monomer derivative has a bifunctional norbornene spiro lactide structure, spiro[6-methyl-1,4-dioxane-2,5-dione-3,2′-bicyclo[2.2.1]hept[5]ene], and structure as follows: and stereoisomers thereof. The lactide monomer derivative is bifunctional in that either 1) the norbornene ring, 2) lactide ring, or 3) both, can be opened and used in polymer synthesis for the backbone or the reactive branch for other polymeric syntheses.

  Polylactic acid-backbone graft and bottlebrush copolymers are synthesized by polymerizing a lactide-functionalized macromonomer using ring opening polymerization (ROP). In some embodiments of the present invention, the macromonomer is a lactide-functionalized polymer that may be synthesized by, for example, polymerizing a monomer capable of undergoing radical polymerization (e.g., styrenic, vinylic, acrylic, etc.) using a brominated lactide initiator via atom transfer radical polymerization (ATRP). The brominated lactide initiator may be 3-bromo-3,6-dimethyl-1,4-dioxane-2,5-dione prepared by, for example, reacting lactide with N-bromosuccinimide in the presence of benzoyl peroxide.

  Polylactic acid-backbone graft and bottlebrush copolymers with low moisture vapor transmission rates are synthesized by polymerizing a lactide-functionalized hydrophobic macromonomer using ring-opening polymerization (ROP). In some embodiments of the present invention, the macromonomer is a lactide-functionalized hydrophobic polymer that may be synthesized by, for example, polymerizing a hydrophobic monomer (e.g., a fluorinated vinyl monomer such as 2,2,2-trifluroethyl methacrylate) capable of undergoing radical polymerization (e.g., styrenic, vinylic, acrylic, etc.) using a brominated lactide initiator via atom transfer radical polymerization (ATRP). The brominated lactide initiator may be 3-bromo-3,6-dimethyl-1,4-dioxane-2,5-dione prepared by, for example, reacting lactide with N-bromosuccinimide in the presence of benzoyl peroxide.
