Biodegradation of Polyurethane Derived from Castor Oil
The aim of this research was to study the biodegradation of a polymer derived from castor oil, which is a renewable, natural material that is a practical alternative for the replacement of traditional polyurethane foams. Due to its molecular structure, which contains polyester segments derived from vegetable oil, the polymeric surface is susceptible to microorganism attack. This study tested th...
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 کاملDiametral tensile strength and film thickness of an experimental dental luting agent derived from castor oil
UNLABELLED The need to develop new dental luting agents in order to improve the success of treatments has greatly motivated research. OBJECTIVE The aim of this study was to evaluate the diametral tensile strength (DTS) and film thickness (FT) of an experimental dental luting agent derived from castor oil (COP) with or without addition of different quantities of filler (calcium carbonate - CaC...
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...
متن کاملTransdermal Absorption of Castor Oil
With the current high level of interest in patches to deliver drugs across the skin, the concept of external applications for delivery of medicinal substances is becoming widely accepted. This study evaluated the potential for transdermal absorption of castor oil, a treatment modality recommended by Edgar Cayce. Specific epoxydicarboxylic acids are known to be excreted via the urine when castor...
