Pushing the Limits for Thiol−Ene and CuAAC Reactions: Synthesis of a 6th Generation Dendrimer in a Single Day

Dendrimer synthesis should not be tedious and time-consuming. By utilizing an AB2−CD2 approach and having orthogonal, “clickable” groups on each monomer, the time for dendrimer assembly can be drastically reduced. This was shown by preparation of a sixth generation dendrimer from starting monomer units in a single day

Rheological behaviour during UV-curing of a star-branched polyester

Using a rheometer coupled with an UV-light generator, the viscoelastic behaviour during the fast cure of star-branched polyester is investigated. The 32 arm star polymers consist of a hyperbranched polyester core, BoltornTM and linear grafts of poly(E-caprolactone) (degree of polymerisation: 20.52) with methacrylate end groups. The resins are crystalline and the melting points range from 34 to 50 .C; films can be formed and cured below 80 .C. The crossover of G. and G.. was used as the gel point. The time to reach the gel point, a few seconds, increases linearly with molecular weight
