Introducing polar functionalities to polyolefins such as polyethylene and polypropylene is highly desirable for improving physical properties of the otherwise non-polar material. The synthesis stereoregular functionalized polyolefins, however, has been a relatively underdeveloped area compared that because lack suitable catalysts tolerate groups while possessing stereoselectivity. This review s...

The curing of epoxy-anhydride vitrimers involves anionic copolymerization epoxide and anhydride along with homopolymerization excess epoxide, giving rise to a poly(ester-co-ether) network. By monitoring using infrared spectroscopy in different conditions mapping the presence OH groups, we demonstrate that generation hydroxide necessary for transesterification, exclusively relies on side reactio...

heterogeneous ziegler-natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. in our previous study, it was reported that mgcl2-supported titanocenecatalysts can generate both ziegler-natta-type and metallocene-type active sites according to the type of activators.the dual active site nature of the supported titanocene catalysts was furt...

We develop a simple recursive approach to treat reversible condensation polymerization with cyclization. Based upon minimum set of balance equations, the law mass action, Gaussian chain statistics, and assumption independent reactions, we derive exact analytical solutions for systems without cyclization, containing only smallest loops, or that exclusively form loops. Exact numerical are compute...

The data on the synthesis of new monomer benzamidmetacrylate are presented in article. Its composition and structure were established by physical chemical methods research. regularities radical homopolymerization reactions mass benzene solution studied with aim creating a biocidal polymeric material for medical preparations. It is shown that polymerization under these conditions proceeds throug...

In a preceding work [ Macromolecules 2021, DOI: 10.1021/acs.macromol.1c00718], we have introduced simple recursive scheme that allows us to treat stepwise linear reversible polymerizations of any kind with cyclization. This approach is used discuss the polymerization Gaussian strands (LGS) two different reactive groups A and B on either chain end participate in orthogonal reactions strictly alt...
