###### Abstract  
This research presents a synthesis and characterization of new bio-based polymer sorbents. Natural origin substances such as terpenes (citral, limonene, and pinene) or vegetable oils (argan, linseed, and rapeseed oils) were used as monomers, and divinylbenzene was applied as the cross-linker. The newly prepared polymers were characterized by means of ATR-FTIR, TG/DTG and titration methods (acid and iodine values), and N\({}_{2}\) physisorption experiments. Tests of sorption ability were carried out by a dynamic solid phase extraction method using a mixture of four phenols or single-component pharmaceutical solutions (salicylic acid, aspirin, ibuprofen, paracetamol, and ampicillin). The performed studies revealed that the terpene-based polymers possessed better-developed porous structures (420-500 m\({}^{2}\)/g) with more uniform pores than oil-based ones. However, the surface of the oil-based sorbents was more acidic in nature. The sorption tests showed that both the porosity and acidity of the surface significantly influenced the sorption. Recoveries of up to 90% were obtained for 2\(A\) dichlorophenol from C-DVB, L-DVB, and Ro-DVB. The lowest affinity to the polymers exhibited phenol (5-45%), aspirin (1-7%), and ampicillin (1-7%). A 70% recovery was achieved for ibuprofen from C-DVB. In-depth data analysis allowed the influence of various factors on the sorption process of test compounds of the studied polymers to be elucidated. p 2022145389 14 53  
moieties, such as hydroxyl, aldehyde, ketone, or oxygen carboxyl groups. For this reason, terpenoids have very similar physical properties to terpen; however, they are more polar. Higher polarity results in slightly better water solubility and a little less volatility in comparison to terpenes [1]. The biological activity of terpenes and terpenoids allows them to be used as ingredients in natural medicines and pharmaceuticals, as well as within plant protection agents (natural pesticides). Their characteristic flavors and pleasant fragrances provide them with wide and common applications in the food, cosmetics, and perfumery industries. Due to their ability to dissolve various substances, terpene compounds are utilized as degreasing and cleaning products and organic solvents. Chemical reactivity is the reason for terpenes and their derivatives to be applied as reagents in chemical syntheses. They can also constitute a feedstock for the chemical industry, e.g., in the preparation of adhesives, varnishes, inks, paints, etc. [1; 3]. Terpenes and terpenoids have also been used in the synthesis of polymeric materials as monomers that meet the requirements of green and sustainable chemistry [4]. Natural features of terpenes, such as lipophilicity, liquid crystallinity, bioactivity, and biodegradability, make the polymers produced out of them useful in many applications. In order to obtain polytepenes, chain-growth and step-growth polymerizations with appropriately selected catalysts have been designed [3; 5; 6]. Polymerizations of terpene-based monomers have also been widely used. In this approach, terpenes are chemically modified to give new monomers with unique properties. Succinic or maleic anhydrides [3; 6; 7], acid chlorides, or methyl methacrylate [3] are examples of popular compounds, the use of which obtains new terpene-based polyesters. In turn, the utilization of citric aminoamide [8] enables the synthesis of polyurethanes. There are also known methods to obtain polymers with pendent terpenes entities using, for example, graft reactions. When attached to the backbone of another polymer, to a greater extent, such terpenes preserve some of their properties, such as biological activity [3]. Intensive scientific works carried out in this field have resulted in many new monomers and polymers, which have opened up great potential in terms of the desired material properties, such as high chemical resistance [7] or recyclability [6]. Vegetable oils composed mainly of triglycerides are another interesting group of unsaturated compounds.
