Synthesis of Unsaturated Polyester Resins from Various Bio-Derived Platform Molecules
Utilisation of bio-derived platform molecules in polymer synthesis has advantages which are, broadly, twofold; to digress from crude oil dependence of the polymer industry and secondly to reduce the environmental impact of the polymer synthesis through the inherent functionality of the bio-derived platform molecules. Bulk polymerisation of bio-derived unsaturated di-acids has been employed to p...
متن کاملRenewable co‐polymers derived from castor oil and limonene*
Biobased monomers derived from castor oil as well as from limonene suitable for thiol–ene copolymerization were synthesized. Di‐10‐undecenylether 2 was obtained via GaBr3‐catalyzed reduction of 10‐undecenyl 10‐undecenoate 1. Diene ether 2 and (R)‐limonene 5 were reacted in two steps using radical thiol–ene addition reactions to dithiol ether 4 and dithiol 7, respectively. Diene ether 2 and dith...
متن کاملThermal Stability and Impact and Flexural Properties of Epoxy Resins/Epoxidized Castor Oil/Nano-CaCO3 Ternary Systems
Epoxy ternary systems were prepared from the diglycidylether of bisphenol-A (DGEBA), epoxidized castor oil (ECO), and nano-CaCO3 using a thermally latent initiator. The effects of ECO and the nano-CaCO3 contents on the thermal stability and mechanical interfacial properties of the prepared DGEBA/ECO/nano-CaCO3 ternary systems were examined by thermogravimetric analysis (TGA), Izod impact tests,...
متن کاملMicrowave and Conventional Mechanical & Thermal Analysis of the Reactions in Epoxy Vinyl Ester Resins
Over a billion microwave ovens are used every day thus witnessing the importance of microwave heating in the world today. Microwave processing of polymers is a comparatively recent and vastly expanding field in industry due to economical advantages through energy saving and accelerated manufacture. Factors that hinder the use of microwaves in materials processing are decreasing every day. Epoxy...
متن کاملPolyol from castor oil and epoxy resin for PU Coatings
Novel reactive polyols were synthesized via modification of castor oil, a renewable agricultural raw material with epoxy resin and triethylamine as a catalyst. This polyol was used for synthesis of polyurethane coating. Coating formulations were developed by reacting polyol with aromatic adduct, aliphatic adduct and castor oil based adduct in different NCO/OH ratio. All coating composition syst...
