“…Catalytic chain transfer from ETM catalysts to zinc has also been applied and led to the synthesis of polyolefins bearing alkyne or azide functionalities. 147 For a more general overview of the potential of catalytic chain transfer to zinc in polymerisation, see e.g. Gibson, 148 Arriola 149 and Sita 150 and references therein.…”

Synthesis of functional ‘polyolefins’: state of the art and remaining challenges

Functional polyolefins (i.e., polyethene or polypropene bearing functional groups) are highly desired materials, due to their beneficial surface properties. Many different pathways exist for the synthesis of these materials, each with its own advantages and drawbacks. This review focuses on those synthetic pathways that build up a polymer chain from ethene/propene and functionalised polar vinyl monomers. Despite many recent advances in the various fields of olefin polymerisation, it still remains a challenge to synthesise high molecular-weight copolymers with tuneable amounts of functional groups, preferably with consecutive insertions of polar monomers occurring in a stereoselective way. To overcome some of these challenges, polymerisation of alternative functionalised monomers is explored as well.

Long-chain branching plays an important role in the performance of polyolefi ns (POs). The existence of a very small amount of long-chain branches (LCBs), i.e., <1 per 10 000 carbons, can signifi cantly improve processability of the polyolefi n materials, which is highly desired for those intractable polyolefi ns with narrow molecular weight distribution and high degree of crystallinity. Numerous literatures have been published on the controlled synthesis of long-chain-branched POs. In the previous paper, the major literatures of single catalyst systems have been summarized. This paper provides a comprehensive review for the binary and multiple catalyst systems and a brief summary of some other methods for the controlled synthesis of long-chainbranched POs. The controllability of long-chain-branched structures in the various preparation procedures with single or two reactor systems, and in one or two-step processes, is analyzed and compared in-depth. world polymer market. In the recent years, shortage in the fossil fuel resources has powerfully stimulated the technological innovation and improvement of the PO industry, as the monomers such as ethylene and propylene are originally based on nonrenewable crude oil refi ning. A Comprehensive Review on ControlledPOs are widely used in various application areas due to their good physical and mechanical properties, superior processability, good chemical and environmental resistance, good recyclability, and low costs. The good performance of PO materials intrinsically depends on its chain microstructure, [ 1,2 ] which includes three major aspects: molecular weight (MW) and molecular weight distribution (MWD), short-chain branching, and long-chain branching. Therefore, the tailor design of PO materials requires at least good control of these three basic structure elements.(1) Control of MWs and MWDs : POs with a narrow MWD have less solvent-extractable components, i.e., those

“…Azide–alkyne click chemistry has been used for the surface functionalization of gold, silica, magnetic nanoparticles, carbon nanotubes, metal‐organic frameworks, and semiconductor surfaces (Chen et al, 2019; Nebhani & Barner‐Kowollik, 2009). Azide–alkyne click chemistry‐based functionalization of polymers like PP or PET was reported through the incorporation of reactive groups during polymer synthesis or postpolymerization treatment (Yameen et al, 2010; Zhang et al, 2011). Functionalisation of unmodified PP or PET by azide–alkyne click chemistry has, to the best of our knowledge, not been reported yet.…”

A versatile peptide‐based toolbox for surface functionalization was established by a combination of a universal material binding peptide (LCI‐anchor peptide) and sortase‐mediated bioconjugation (sortagging). This toolbox facilitates surface functionalization either as a one‐ or a two‐step strategy. In the case of the one‐step strategy, the desired functionality was directly introduced to LCI. For the two‐step strategy, LCI was modified with a reactive group, which can be further functionalized (e.g., employing “click” chemistry). Sortagging of LCI, employing sortase A from Staphylococcus aureus, was achieved with six different amine compounds: dibenzocyclooctyne amine, biotin‐polyethylene glycol amine, Cyanine‐3 amine, kanamycin, methoxypolyethylene glycol amine (Mn = 5000 Da), and 2,2,3,3,4,4,4‐Heptafluorobutylamine. The purification of LCI‐amine sortagging products was performed by a negative purification using Strep‐tag II affinity chromatography, resulting in LCI‐amine conjugates with purities >90%. For the two‐step strategy, the LCI‐dibenzocyclooctyne sortagging product was purified and enabled, through copper‐free azide–alkyne “click” chemistry, universal surface functionalization of material surfaces such as polypropylene, polyethylene terephthalate, stainless steel, gold, and silicon. The click reaction was performed before or after surface binding of LCI‐dibenzocyclooctyne. Finally, in the case of the one‐step strategy, polypropylene was directly functionalized with Cyanine‐3 and biotin‐polyethylene glycol amine.
