Automated Solvent‐Free Polymerization of Hyperbranched Polyglycerol with Tailored Molecular Weight by Online Torque Detection

Fluorescent bimanes are low molecular weight and low toxicity molecules with applications ranging from biology to LASER dyes. The widespread use of these molecular probes has presumably been stalled by the hazards involved in their current synthetic preparation which involve handling of dangerous halogens like chlorine (gas) and bromine (liq.). The accessibility achieved by the simple and safe dihalogen and solvent-free methodologies described here open the floodgates to additional future practical applications of bimanes.

The Difference

AbstractA high temperature resistant novolac cyanate ester was blended with polyethersulfone (PES) with different molecular weights using the solvent-free approach. The phase separation, curing behavior and thermal properties were studied using hot stage microscopy, differential scanning calorimetry and dynamic mechanical analysis. Results showed the difference in the morphology for blends with different molecular weight PES explained by possible network formation. The influence of PES content on the glass transition temperature and mechanical properties was investigated. The most significant toughening effect (increase of 132% in fracture toughness) was achieved on a functionalized low molecular weight PES (20 parts per hundred of resin, phr). Rheology investigation allowed to estimate the optimal content of PES (15 phr) for further prepreg manufacturing.
