December 06th, 2017 – Deep eutectic solvents (DES): Excellent green solvents for rapid SARA ATRP of biorelevant hydrophilic monomers at ambient temperature
Recently, our group reported an eco-friendly type III deep eutectic solvent (reline: choline/urea mixture) for the polymerization of different bio-relevant hydrophilic monomers (HEA: 2-hydroxyethyl acrylate, HEMA: 2-hydroxyethyl methacrylate and AMPTMA: (3-acrylamidopropyl)trimethylammonium chloride) through supplemental activator and reducing agent atom transfer radical polymerization (SARA ATRP) near to room temperature (30 ºC). The polymerization of PHEA was mediated by a safe and inexpensive SARA agent (sodium dithionite: Na2S2O4), and the results showed that a slow and continuous feeding of the SARA agent to the reaction mixture allows a PHEA-Br with higher chain-end functionality and lower dispersity (Ð ≈ 1.1) in comparison to the obtained without Na2S2O4 feeding.
May 04th, 2017 – Free Seminar: Biopolymers in the Industry – Current State and Perspectives
The polysyc group and the Chemical Engineering Department (DEQ) of the University of Coimbra (FCTUC) invite all the interested to attend the free seminar that will take place on Thursday May 4th 2017, from 14h30 to 18h on the Noble Amphitheater of DEQ/FCTUC. The seminar will intend to provide an integrated and objective vision about the industrial application potential of new biopolymers.
The seminar will count with the presence of 4 speakers:
Engineer José Varela (responsible for BASF business development);
Engineer Jordi Serda (28 years experience in the plastic work field at the BASF);
Engineer Susana Carvalho (Executive Administrator at Resiquímica, with a wide experience in the application of biopolymers in paints and composites);
Prof. Arménio Serra (Assistant Professor at University of Coimbra).
The entrance is free. However, a pre-inscription is required via e-mail to firstname.lastname@example.org until April 28th 2017 due to space limit with “Inscrição Seminário Biopolímeros na Industría” as subject, and the following data:
