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.

聚合物无处不在，并且有望在许多应用中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单元（单体）来生成新的聚合物材料。在这个提案中，我们打算以创新的方式结合最简单的构建单元（乙烯和简单的极性单体），从而产生全新的聚合物材料。 因此，我们建议探索后过渡金属配合物催化乙烯与极性单体的共聚。 将通过乙烯与丙烯酸酯、丙烯酸和丙烯酰胺的催化共聚来制备一类新型聚合物。将仔细研究丙烯酸烯丙酯的环化聚合，并制备乙烯和丙烯酰胺的两亲性共聚物，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三羰基铬的双金属膦磺酸盐的聚合催化剂。
