“…To vary the polymerization method, a promising environmental friendly route to poly(lauryl acrylate) was proposed by using single-electron transfer/degenerative chain transfer living radical polymerization (SET/DTLRP). 219 The polymerization was catalyzed by Na2S2O4 and was conducted in aqueous media. In this way, α,ω-diiodo-poly(lauryl acrylate) was obtained which can be further used as a macro-initiator.…”

“…It is observed that on grafting the paper exhibits a less noticeable fibrillary structure. Both, polymers pLA and pOA present glass transition temperatures below room temperature, thus they are in a rubber state, and their chains are mobile enough to promote the fiber aggregation through multiple chain entanglement. These observations agree with previous reports of acrylic polymers grafted from cellulose fibers in paper sheets …”

In the present work, cellulose fibers were modified by grafting with poly(lauryl acrylate) and poly(octadecyl acrylate). The grafted materials were prepared by polymerization of the corresponding monomers via surface initiated atom transfer radical polymerization, starting from cellulose papers previously modified with 2-bromoisobutyryl groups. The polymerizations were carried out in the presence of ethyl-2-bromoisobutyrate, as a sacrificial initiator, added to control the molecular weight of the anchored segments, and polymerization kinetics. The grafting of both polymers was confirmed by infrared spectroscopy and elemental analysis. The effect of grafting these polymers on the thermal stability, morphology, and surface properties of cellulose fibers was studied using thermogravimetric analysis, scanning electron microscopy, and measuring water contact angle, respectively. The results reveal that grafting poly(lauryl acrylate) and poly(octadecyl acrylate) to cellulose confers the filter paper a hydrophobic character, and increases its affinity with pyrene, allowing the removal of this pollutant from water.

“…(Figure 6a (i)) that act as TPEs (Figure 6a (ii)) [89]. A copolymer of LAc and SAc has been chosen as the midblock of the triblock copolymers as these monomers offer a number of advantages, including low glass transition temperatures [90,91] and long alkyl side chains that are highly hydrophobic and provide greater resistance to degradation [92]. Varying the length of the side chain on the polyacrylate midblock (C18 and C12 in stearyl and lauryl acrylate repeat units, respectively) is a convenient tool for tuning the physical properties of the triblock copolymers.…”

Block copolymers including ABA triblock architectures are useful as thermoplastic elastomers and toughened plastics depending on the relative glassy and rubbery content. These materials can be blended with other polymers and utilized as additives, toughening agents, and compatibilizers. Most of commercially available block copolymers are derived from petroleum. Renewable alternatives are attractive considering the finite supply of fossil resources on earth and the overall economic and environmental expenses involved in the recovery and use of oil. Furthermore, tomorrow's sustainable materials are demanding the design and implementation with programmed end-of-life. The present review focuses on the preparation and evaluation of new classes of renewable ABA triblock copolymers and also emphasizes on the use of carbohydrate-derived poly(lactide) or plant-based poly(olefins) having a high glass transition temperature and/or high melting temperature for the hard phase in addition to the use of bio-based amorphous hydrocarbon polymers with a low glass transition temperature for the soft components. The combination of multiple controlled polymerizations has proven to be a powerful approach. Precision-controlled synthesis of these hybrid macromolecules has led to the development of new elastomers and tough plastics offering renewability, biodegradability, and high performance.
