We report the synthesis of PE and poly(ethylene-co-vinyl acetate) (EVA) bearing a low content in-chain thioester functions introduced via co- or terpolymerization approach involving ethylene (E), vinyl acetate (VAc), ε-thionocaprolactone (TCL). To achieve homogeneous incorporation along chains resulting from ring opening TCL, semibatch process with an adjusted feed TCL was employed. Characterizations polymers were conducted by combination size exclusion chromatography (SEC) nuclear magnetic resonance (NMR) analyses. The chemically induced degradability obtained assessed SEC.

Polymer research is currently focused on sustainable and degradable polymers which are cheap, easy to synthesize, environmentally friendly. Silicon-based thermally stable can be utilized in various applications, such as columns coatings. Poly(silyl ether)s (PSEs) an interesting class of silicon-based that easily hydrolyzed either acidic or basic conditions due the presence silyl ether Si-O-C bond. Synthetically, these formed several different ways, most effective friendly synthesis dehydrogenative cross coupling, where byproduct H

To establish a sustainable society, the development of polymer materials capable reverting into monomers on demand is crucial. Traditional methods rely breaking labile bonds such as esters in main chain, which limits applicability to polymers that consist robust covalent bonds. We found integration directing groups allowed engineering resilient with built-in recyclability. Our study showcases phenylene ether-based fortified groups, can be selectively disassembled under nickel catalysts

Abstract Developing plastics that fill the need of polyolefins yet are more easily recyclable is a critical to address plastic waste crisis. However, most efforts in this vein have focused on high‐density polyethylene (PE), while many different types PE exist. To create broadly sustainable with modular properties, we present synthesis, characterization, and demonstration materials applications for chemically PE‐like multiblock polymers prepared from distinct hard soft blocks using ruthenium‐catalyzed dehydrogenative polymerization. By altering branching pattern within blocks, series were synthesized tunable glass transition temperatures ( T g ) maintaining consistent high melting m ). A clear U‐shape trend between mechanical properties was found, showcasing their potential as tailored spanning commercial linear low‐density (LLDPE) (LDPE). These offer adjustable adhesive strength metal demonstrate chemical recyclability selective depolymerization mixed streams, promoting circularity separation.
