Researchers from Brazil performed an experiment to evaluate the feasibility of OSB Castor oilpanel production Parica (Schizolobium amazonicum) wood particles bonded by castor oil based polyurethane resin. Three different resin contents (8%, 10% and 12%) were evaluated.

Results showed that panels produced with 8% of resin content were best as they were compatible with norm requirements and used less resin in the manufacturing process. Thus Parica wood and castor oil based polyurethane resin in the OSB panels production is feasible.

Scientists from Italy conducted an experiment to synthesize electroactive polyurethane/siloxane films from castor oil for use as a cardiac patch. The electroactive films containing aniline tetramer were prepared through sol gel reaction of trimetcastor oil polyurethanehoxysilane functional intermediate polyurethane prepolymers obtained from castor oil and polyethylene glycol.

Physicochemical, mechanical and electrical conductivity of samples were evaluated and correlated with their structural characteristics. Results showed that the prepared films were compatible with proliferation of C2C12 and had the potential to enhance myotube formation even without electrical stimulation.

Scientists from Japan conducted an experiment to increase the toughness of poly(L-lactide) (PLLA) with the help of polyester urethane networks obtained from castor oil based oligomers.  Hydroxy-terminated castor oil-modified ɛ-castor oilcaprolactone oligomers (CO-CLOns) were prepared by ring opening polymerizations of ɛ-caprolactone initiated with castor oil. It was then allowed to react with poly(L-lactide) which produced semi-interpenetrating polymer networks composed of TDI-bridged CO-CLOn networksand PLLA.

DSC analysis revealed that TCO-CLO10/PLLA 75/25 exhibited the highest tensile toughness compared to other polymer networks.

Scientists from Turkey conducted a study to investigate a new type of bifunctional Castor oilmonomer obtained from castor oil. Castor oil was first reacted with acryloyl chloride to obtain acrylated castor oil. Epoxidized acrylated castor oil obtained after epoxidation reaction was characterized using various techniques.

After characterization, homo and block copolymers were synthesized and evaluated. It was observed that epoxidized acrylated castor oil copolymer showed higher storage modulus and higher thermal stability.

Scientists from India conducted an experiment to prepare functionalized castor oil derivatives with tunable physical properties by using heterogeneous acid and base catalysts. Epoxidized castor oil (ECO) was used as a raw material to prepCastor oilare the different functionalized castor oil derivatives namely ring-opened glyceryl ricinoleates, epoxy alkyl ricinoleates, and ring-opened alkyl ricinoleates, using two chemical reactions, ring opening and transesterification.

Among several acid catalysts screened, Amberlyst 15 showed maximum conversion for ring opening of ECO with methanol. By using CaAl-layered double hydroxide (LDH) derived oxides as base catalyst, maximum yield of epoxy alkyl ricinoleates were obtained through transesterification of ECO. The physical properties of these derivatives can be used to design tailor-make material for industrial needs.
