###### Abstract
These are relatively cheap and easy-to-obtain substances. The most common and obvious use of vegetable fats and oils is in the consumption food industries. However, their applications in other fields are also well-known. These result from the specific properties of vegetable oils, which are a consequence of the unique chemical composition of glycerolipides (Table 1). Argan oil, known as the \"liquid gold of Morocco\", is famous for its cosmetic applications [9; 11; 12; 13], but it also can be used as a costabilizer in miniemulsion polymerization [14]. Linseed oil is utilized in pharmaceutical and cosmetic products (e.g., soaps), but also as an industrial raw material for the production of wood preservatives (especially those with hydrophobic properties). Various preparations based on this oil are used as binders and media in painting or the restoration of works of art and antiques [15]. Rapeseed oil can be applied as a fuel or admixture with diesel oil; it is also a raw material for the production of biofuels such as biodiesel [16; 17; 18]. \begin{table}

Table 1: Mean values of fatty acid composition in oils. In the era of dwindling natural resources, new sources of chemical reagents are sought that will be able to partially or completely replace the current petroleum-derived substrates. Hence, there is a constant increase in the use of unsaturated compounds of natural origin [10; 19]. In particular, many industrial applications do not require compounds of the highest quality, as is demanded in the food or pharmaceutical industries. Indeed, a desirable direction is the search for management methods:  
* Post-production waste, (e.g., post-extraction residues),
* The utilization of substrates that are unsuitable for specific purposes, e.g., pharmaceutical production due to lower quality or food purposes because of expiring shelf life,
* Exploiting matter that is not suitable for further use (e.g., post-frying oils). Often the final stage of using such substances is adding them to fuels for energy retrieval purposes. An alternative may be the production of polymeric materials. According to the typical chain-growth polymerization mechanism, natural triglycerides react slowly; therefore, in order to increase their reactivity, methods based on initial chemical modification have been proposed, e.g. oxidation of the double bond to the epoxide which, after hydrolysis, gives diols used in the preparation of polyurethanes. The epoxidized intermediate may also condense with acrylic/methacrylic acid, ester, or amides to form new monomers suitable for thermoset plastic production [19]. They can also be copolymerized with, for example, styrene, which significantly expands the possibilities of obtaining polymers with various properties, from rigid and hard cross-links to soft rubber-like ones.
