Catalytic polymerization of ethylene with polar monomers

聚合物无处不在，有望在许多领域取代传统的结构材料。为此，有必要基于化学家容易获得的一组狭窄的构建块(单体)来生成新的聚合物材料。在这个方案中，我们打算以一种创新的方式将最简单的构建基块(乙烯和简单的极性单体)结合在一起，从而生成全新的聚合物材料。因此，我们建议探索后过渡金属络合物催化乙烯与极性单体的共聚。通过乙烯与丙烯酸酯、丙烯酸和丙烯酰胺的催化共聚，将得到一种新型的聚合物家族。我们将仔细研究丙烯酸烯丙酯的环聚反应，并将制备两亲性共聚物乙烯和丙烯酰胺，目标是在水中产生自组装纳米结构。我们还将合成一系列基于亚氨基磺酸盐和含有芳基铬三羰基的双金属膦磺酸盐的聚合催化剂。

Polymers are ubiquitous, and are expected to be able to replace traditional structural materials for many applications. For this purpose, it is necessary to generate new polymeric materials based on the narrow set of building blocks (monomers) which are easily accessible to the chemist. In this proposal, we intend to combine the simplest building blocks (ethylene and simple polar monomers) in an innovative manner, so as to generate entirely novel polymeric materials.  Thus, we propose to explore the copolymerization of ethylene with polar monomers catalyzed by late transition metal complexes.  A novel family of polymers will be prepared by the catalytic copolymerization of ethylene with acrylic esters, acrylic acid and acrylamides. The cyclopolymerization of allyl acrylate will be scrutinized, and amphiphilic copolymers ethylene and acrylamide will be prepared with the goal to generate self-assembled nanostructures in water.  We will also synthesize a family of polymerization catalysts based on imino-sulfonates and bimetallic phosphine-sulfonates containing aryl chromium tricarbonyls.
