Development of vegetable‐oil‐based polymers

Abstract

The utilization of renewable resources for the preparation of new materials is an alternative option for reducing the high demand of fossil feedstocks. Vegetable oils are potential bioresources that are renewable and abundantly available. Triglyceride-based vegetable oils, such as soybean, jatropha, linseed, sunflower, palm, castor, nahar seed, and canola oil, are being considered as precursors in the production of polymers. In this article, we attempt to summarize advancements in processes and technologies for the synthesis of polymers from various kinds of vegetable oils. The advantages and disadvantages of these biobased polymers with respect to traditional monomer-based ones are also highlighted.

Synthesis and Characterization of Poly (ester-amide) of Adipic Acid and Fatty Amide of Melia Azedarach Seed Oil – An Eco-friendly Resource

“…Among different renewable resources vegetable oils obtained from seeds of various plants are in the spotlight of the chemical industries as they are the abundantly available in nature and also show low eco-toxicity as well as low-toxicity towards humans [4,5]. Common traditional seed oils such as linseed, sunflower, castor, soybean, coconut are being largely used in the synthesis of polymers like alkyds, epoxies, polyurethanes, interpenetrating polymer networks (IPN)s, poly (ester-amide)s and many others [4,[6][7][8][9][10]. These polymers are extensively used as coatings, adhesives, insulators and biomedical structures.…”

Biodegradable polymers from monomers based on vegetable oils

“…Fatty acids account for 95 % of the total weight of triglycerides and their structures depend on the biological source and growing conditions [1, 4,5,8,9]. A list of the most common fatty acids present in vegetable oils is summarized in Table 1.…”

“…The chain length (or averaged molar mass) of all the fatty acids in the vegetable oil can be determinated by the saponification value. The long-chain fatty acids found in vegetable oil have a low saponification value due to their relatively low number of ester groups per unit mass of the oil, while the short-chain fatty acids have a higher value [8]. The degree of unsaturation is measured by the iodine value.…”

Urethane-Modified Boron Containing Polyesteramide of Phthalic Acid from Jatropha Curcas Seed Oil

“…Furthermore, environmental legislations also force to search bio-based alternatives 4,5 . Among different bio-based renewable resources, vegetable oil of different seeds has served as viable alternatives due their low toxicity, inherent biodegradability and easy availability 4,6,7 .…”

“…Among different bio-based renewable resources, vegetable oil of different seeds has served as viable alternatives due their low toxicity, inherent biodegradability and easy availability 4,6,7 . Numerous vegetable oils like soybean, castor, sunflower and linseed have been utilized for the preparations of valuable polymers like alkyds 4 , polyesteramides 8 , polyurethanes 8 , polyamides 4,8 and many others. However among these oils most of them are edible and some of them also posses' medicinal values.…”
