Project 3 Sample Clauses

Project 3. Scalable Resin Formulation via Twin Screw Twin Screw Extrusion (JCATI) - 1.5 student, 2 faculty ▇▇▇▇▇ - ▇▇▇▇▇▇, shared technician Use a twin-screw extruder as a continuous reactor to synthesize gallon-scale quantities of benzoxazine monomers which will perform as reactive diluents within Huntsman’s ▇▇▇▇▇▇▇▇ ▇▇ ▇▇▇▇▇ FST benzoxazine to improve processability in prepreg and RTM manufacturing. Further, blends of MT 35710 FST and reactive diluents will be formulated with additional additives such as liquid flame-retardants and cure accelerators to maintain FST compliancy and further improve processing properties such as injection viscosity and cure time. Project 4 – Compatiblizing BO resins with polymerizable surfactants – 2 students, 3 faculty weeks - Rider, shared technician We are interested in further developing water-based BO resins take utilize surfactants to stabilize hydrophobic BO resin monomers in water. The surfactants are synthesized by us and are PEGylated BO molecules. In an effort to more fully understand the structure-property relationships for loading capacity, cure kinetics, and applicability of water-based BO resins that utilize these surfactants, we would like to elaborate the structure of the PEGylated BO molecules. Specifically, we would like to study (i) a double-headed analogue [(BO)2-mPEG] where two BO molecules are found at a chain end of a methoxy-caped polyethylene glycol and (ii) an analogue where both chain ends of the polyethylene glycol are functionalized with a single BO monomer [(BO)-mPEG-(BO)]. The synthesis of the doubly-headed (BO)2-mPEG target is shown in Scheme 1. The synthesis of the polyethylene glycol with both of its chain ends functionalized with BO monomers (BO)-mPEG-(BO) is shown in Scheme 2. We wish to synthesize, characterize and utilize these polymerizable molecules to compatiblize other BO resin monomers with water for water-based processing.
