Catalysis for controlled polymerization

Nowadays, single-site metal catalyzed polymerization represents a powerful tool for the controlled, environmentally friendly, synthesis of new and old polymeric materials.

The main research topic of Prof. Barbara Milani deals with the development of homogeneous catalysts for polymerization. Two polymerization reactions are currently under investigation:

1. Ethylene/polar vinyl monomer copolymerization

2. CO/vinyl arene copolymerization

These two reactions share the catalysts that are based on palladium(II) complexes with nitrogen-donor ligands.

1. The synthesis of ethylene/polar monomer copolymers via the homogeneously catalyzed, direct copolymerization of the two comonomers represents one of the major unsolved problem in the field of polymer chemistry. The aim of this research is focused on the discovery of a catalyst able to efficiently carry out the reaction under mild conditions of temperature and pressure, leading to the copolymer with a content of the polar monomer of at least 20 % and with the polar monomer inserted into the main polymer chain.

2. Prof. Milani has a consolidate, nationally and internationally recognized experience in the development of homogeneous catalysts for the controlled synthesis of CO/vinyl arene polyketones via the direct copolymerization of the two comonomers. Two major issues have been and are currently addressed: catalyst stability and polymer stereochemistry.

The research activity of Prof. Milani is internationally recognized as demonstrated by the fact she is the coordinator of Working Group 2 “CO_x activation” inside the COST Action CM1205 – CARISMA.

People

Prof. Milani’s research group is mainly formed by a PhD student, some master and bachelor students working on a research project for their master and bachelor thesis, and occasionally, depending on the available research funds, a post-doc is also appointed. In the group are regularly hosted PhD students and post-doc coming from reasearch groups of the COST Action CARISMA.

In addition, for her research activity Prof. Milani has consolidate and successful collaborations with several National and International research groups. In particular, inside her Department she regularly collaborates with: Prof. Enzo Alessio, Prof. Elisabetta Iengo, Prof. Ennio Zangrando, Dr. Gabriele Balducci, Prof. Paolo Fornasiero, Dr. Tiziano Montini, and Prof. Fulvia Felluga.

Currently, the members of the research group are:

Francesca Milocco Master student in Chemistry

Vera Rosar PhD student
