Abstract: A self-healing composite material includes a polymer matrix, microcapsules filled with a ring-opening metathesis-active monomer (e.g., norbornene, norbornene derivatives such as ethylidene norbornene, or cyclooctadiene), and polymeric particles comprised of a polymer that is soluble in the monomer with which the microcapsules are filled and having catalytic endgroups derived from an olefin metathesis catalyst, such as a Grubbs'-type catalyst. In some embodiments, the polymer having catalytic endgroups is synthesized via solution polymerization of a ring-opening metathesis-active monomer (e.g., norbornene, norbornene derivatives, or cyclooctadiene) in the presence of an olefin metathesis catalyst (e.g., Grubbs' 1st generation catalyst). The polymer having catalytic endgroups may then be processed via a grinding operation, for example, to prepare the small polymeric particles. In other embodiments, the polymeric particles are synthesized directly as microparticles (e.g., microspheres, granules, beads, etc.

Abstract: A block copolymer is synthesized by polymerizing a silane-functionalized norbornene monomer in the presence of a catalyst system that includes a Ziegler-Natta catalyst and cocatalyst, followed by sequential addition and polymerization of a matrix-reactive functionalized norbornene monomer. In some embodiments, an enhanced substrate for a PCB is produced by applying the block copolymer to a substrate that includes glass fiber, followed by applying the base polymer to the substrate having the block copolymer applied thereto.

Abstract: A flame retardant block copolymer is prepared from renewable content. In an exemplary synthetic method, a bio-derived flame retardant block copolymer is prepared by a ring opening polymerization of a biobased cyclic ester and a phosphorus-containing polymer. In some embodiments, the biobased cyclic ester is lactide. In some embodiments, the phosphorus-containing polymer is a hydroxyl-telechelic flame retardant biopolymer prepared by a polycondensation reaction of a biobased diol (e.g., isosorbide) and a phosphorus-containing monomer (e.g., phenylphosphonic dichloride). In other embodiments, the phosphorus-containing polymer is synthesized from a dioxaphospholane monomer.

Abstract: 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.
