Effects of Vegetable Oil Composition on Epoxidation Kinetics and Physical Properties

In this article, we investigate the role of triacylglycerol composition on the properties of epoxidized vegetable oils and the kinetics of the epoxidation process under conditions comparable to commercial epoxidation. Commodity soybean oil (24% oleic acid, 50% linoleic acid, and 7% linolenic acid), high‐oleic soybean oil (75% oleic acid, 8% linoleic acid, and 2.5% linolenic acid), and linseed oil (11% oleic acid, 15% linoleic acid, and 64% linolenic acid) were each epoxidized to various extents. Epoxidation rate, viscosity, differential calorimetry, and X‐ray diffraction data are presented for these oils and interpreted in the context of their fatty acid profile (mostly oleic, linoleic, or linolenic). While fully epoxidized soybean oil is widely commercially available and used in an increasing array of industrial applications, information relating to partially epoxidized oils and epoxidized oils of other cultivars is less well known.

Preparation of acrylated and urethanated triacylglycerols

Since a preliminary study had shown that the internal double bonds present on the unsaturated aliphatic chains were too unreactive for any viable polymerization process, chemical modifications were investigated involving the grafting of polymerizable moieties on hydroxy or epoxide groups present in castor oil or in epoxidized soybean oil. Acrylate and styrenic urethane moieties were successfully appended on these triacylglycerol molecules. The grafting processes are described and the modified oils characterized, leading to the discussion of some structure‐property relationships.     

Renewable Resin Precursor and Residual Filler Modified Poly(vinyl chloride) Foam,Investigation of Microcellular Development and Moisture Absorption Behavior

Poly(vinyl chloride) plastisol-based foams were prepared with epoxidized soybean oil and residual low cost fillers. Microstructural characterizations using scanning electron microscopy were carried out to understand the microcellular morphology. Absence of epoxy groups in Fourier transform infrared spectroscopy spectra of epoxidized soybean oil-modified–poly(vinyl chloride) plastisol foams indicated the occurrence of ring opening reaction between poly(vinyl chloride) plastisol and epoxidized soybean oil, signifying epoxidized soybean oil’s role as HCl scavenger. X-ray diffraction study indicated increased crystallinity of filler modified poly(vinyl chloride) plastisol/epoxidized soybean oil foams, suggesting their role as possible nucleating agents. Foams with fillers also showed reduced water uptake, which were in good agreement with other characterizations.
