This article deals with enhancement of the toughness of epoxy resin (ER) based on diglycidyl ether bisfenol A by either polydimethylsiloxane (PDMS) or vinyl-terminated polydimethylsiloxane (VT-PDMS). To improve the compatibility of these two phases, dicumylperoxide (DCP) was used as a compatibilizer. It was established that only specific composition of the components can lead to enhancement of ER toughness without significant reduction of storage modulus, T g , and interphase adhesion. The highest impact strength was recorded for ER with VT-PDMS (10 wt %) and DCP (2 wt %) due to increased interfacial compatibility between two phases, which was proved by 1 H NMR and dielectric spectroscopy. Critical ductile brittle transition occurring between 10 and 15 wt % of rubber was observed by both morphological and dynamic mechanical analysis studies. V C 2017 Wiley Periodicals, Inc. J.

“…The crosslinking also enhanced the mechanical properties and crystallinity; this implied that a high‐performance PCL/ENR could be prepared by crosslinking with DCP. Surprisingly, the addition of a high content of DCP resulted in crosslinked PCL/ENR with a more pronounced shear thinning effect and a higher elasticity compared to the uncrosslinked blends …”

PLA was believed to be chemisorbed on the carbon REVIEW WILEYONLINELIBRARY.COM/APP black surface, whereas ENR was believed to be adsorbed physically on the filler surface.…”

At present, the rubber toughening of plastics has become an attractive field of study in polymer science and technology because brittleness is known to be a drawback in many engineering plastics; it can cause premature failure during application. Among existing rubber materials, epoxidized natural rubber (ENR) has been widely used as an impact modifier or toughening agent in a large number of engineering plastics; in particular, it enhances the impact strength, which deteriorates with the incorporation of other additives, such as fillers and flame retardants. ENR is a modification product from natural rubber produced via an epoxidation reaction. ENR also has good chemical resistance. In this review, we aim to provide a concise current status in the field of ENR toughening agents for plastics with a brief discussion of their associated problems and potential applications.

“…Mishra and coworkers [148,149] obtained PCL/ ENR blends cured with dicumyl peroxide. The authors indicated that cross-linking bonds formed in PCL/ENR blends act as a memory point during shrinkage, which improves heat shrinkability and the final mechanical properties of PCL/ENR blends.…”

Abstract.Reactive extrusion is a cost-effective and environmentally-friendly method to produce new materials with enhanced performance properties. At present, reactive extrusion allows in-situ polymerization, modification/functionalization of polymers or chemical bonding of two (or more) immiscible phases, which can be carried out on commonly used extrusion lines. Although reactive extrusion has been known for many years, its application for processing of bio-based polymer blends and composites is a relatively new direction of scientific research. This work presents a literature review on recent advances in the processing of bio-based polymer blends and composites via reactive extrusion. We described compatibilization mechanisms for different types of biodegradable polymeric materials based on: (i) aliphatic polyesters, (ii) aliphatic polyesters/starch and (iii) aliphatic polyester/natural rubber systems. A special attention was focused on conventional and dynamic cross-linking of bio-based polymer blends and composites as an effective way to prepare new materials with unique properties e.g. biodegradable thermoplastic elastomers or shape-memory materials. Advantages and limitations affecting future trends in development of biodegradable polymer blends and composites reactive extrusion are also discussed.
