The levoglucosenone-based norbornenes family was extended to include a new bi-functional methacrylate monomer that, upon ROMP in Cyrene™, leads to polymers with pendent methacrylate moieties which can be modified by post-polymerization reactions.

The simple commercial organomagnesium catalysts were utilized for efficient access to high-molecular-weight poly(γ-butyrolactone) and facile manipulation of the reaction conditions enabled the polymer topology controlled.

We report here the synthesis and polymerization of a novel disubstituted valerolactone, β-acetoxy-δ-methylvalerolactone, derived from the renewable feedstock triacetic acid lactone (TAL).

Photoinduced organocatalyzed atom-transfer radical polymerization (O-ATRP) is a controlled radical polymerization technique that can be driven using low-energy, visible light and makes use of organic photocatalysts.

Spiro polycycloacetals were synthesized from vanillin and syringaldehyde, along with high-performance co-monomers, exhibiting high glass transition temperatures and thermal stabilities, and rapid rates of hydrolysis in acidic solutions.

Lipoic acid provides a modular and bio-sourced platform from which the create covalent adaptable network materials.

Long-chain polyamide covalent adaptable networks with high strength and short relaxation times were prepared based on a renewable ethylene brassylate and disulfide exchange.

A bio-based ferulic acid monomer is inserted in random terpolyesters with high molar mass and offers the possibility of crosslinking after processing. Both ferulate monomer and solvent-free polycondensation make the new materials more sustainable.

Ring opening metathesis polymerization of δ-pinene with varying amounts of α-pinene is explored.

Water-degradable polyvinyl ketals with high glass transition temperatures (78–127 °C) were made via ketalization of polyvinyl alcohol (PVA) with sustainable ketones.

Bio-based lignin-like building blocks were synthesized and transformed into polyurethane nanocarriers by interfacial polymerization in a miniemulsion. The nanocarriers were degradable by fungal enzymes and might be used for agrochemical delivery.

An oxetane derived from D-xylose has been copolymerised with CS₂ into sulfur-containing polymers which are chemically recyclable and degradable under UV light.

The use of photoacid generators for the ring opening polymerization of cyclic esters is investigated.

Polyhydroxyalkanoates (PHAs) are a unique class of polyesters especially due to their chemical diversity imparted by their side-chain substituent that provides a handle to tune their properties, such as their thermal, mechanical and (bio)degradability signature.

Catalytic polymerization in compartmentalized aqueous or non-aqueous media, respectively, with functional-group tolerant Ni(II) catalysts yields low-entangled UHMWPE.

We now report the synthesis of well-defined terpene-based polymers and precise di- and multiblock copolymer architectures by use of RAFT, wide range of T_g and promising adhesive properties are observed.
