Already for a long time, plant oils and their derivatives have been used by polymer chemists due to renewable nature, world wide availability, relatively low price, rich application possibilities. Although many different synthetic approaches used, more recent examples are pointing in the direction of catalytic transformations other efficient reactions achieve sustainable production polymers from these resources. In this context, olefin metathesis, thiol–ene additions, processes can...

Abstract Vegetable oils are excellent renewable raw materials for thermosetting polymers. By the direct polymerization of triglyceride C=C, we obtained organic‐inorganic hybrid with promising properties optical applications by hydrosilylation alkenyl‐terminated fatty acid derivatives. The presence double bonds in triglycerides makes it possible to attach some functional groups through chemical modification, and describe various pathways functionalizing acids. Epoxidation is one most...

Cellulose nanocrystals (CNCs) are widely studied as reinforcing fillers for polymers. In many cases the mechanical properties of polymer/CNC nanocomposites do not match theoretical predictions, arguably on account CNC aggregation. This problem can be mitigated through addition a small amount judiciously selected polymeric dispersant that also serves binder among CNCs. We show 1–5% w/w poly(vinyl alcohol) (PVA) has very significant impact poly(ethylene oxide-co-epichlorohydrin)/CNC...

Within the current contribution, we introduce two strategies for catalyst-free, modular, ambient temperature synthesis of ABC triblock copolymers via photoinduced Diels–Alder reactions. On one hand, 2-formyl-3-methylphenoxy (FMP) moiety (a second generation photoenol precursor) was employed orthogonal polymer–polymer conjugations using terminal acrylates diblock synthesized acyclic-diene-metathesis (ADMET) polymerizations to directly prepare copolymers. other disparate reactivity...

Abstract An increasing number of reports on the syntheses carbohydrate‐ and plant oil‐based polymers has been published in ongoing efforts to produce plastic materials from renewable resources. Although many these are biodegradable this is a desirable property for certain applications, some cases non‐degradable needed long‐term use purposes. Polyolefins one most important classes that have already taken their places our daily life. On other hand, production relies fossil Therefore, within...

A new family of sulfur-containing plasticizers derived from fatty acids has been developed. The synthetic approach is based on the thiol–ene addition alkyl thiols to double bond technical oleic acid, followed by oxidation sulfide group either sulfoxide or sulfone groups. It found that both and derivatives are not suitable as due their unpleasant odor limited thermal stabilities. However, odorless, thermally stable, show plasticizing properties similar those established PVC such...

The stimuli responsiveness of supramolecular polymers has recently been exploited for the development adhesives that can be (de)bonded on demand when heated or exposed to UV light.
