“…Several investigations showed that increasing the carbon chain length was helpful to enhance the flexibility of polyacrylate molecular chain. 27,28 As a result, the longer the carbon chain of acrylate monomer, the more flexible was the molecular chain of the LBG- g -P(AA-co-acrylate) prepared. It can be speculated that the grafted LBG film will exhibit higher elongation at the expense of breaking strength by tensile stress when increasing the carbon chain length of the acrylate.…”

In order to impart good application properties to locust bean gum size for all-polyester yarn, a series of acrylate monomers including methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, and common hydrophilic monomer–acrylic acid were grafted onto molecular chains of native locust bean gum to obtain locust bean gum- g-P(AA-co-acrylate) products with similar grafting ratios through Fenton’s reagent, respectively. The effects of carbon chain length of the series of acrylates on sizing properties of the grafted locust bean gum for polyester warp were studied. It was found that by grafting acrylates onto the molecular chains of locust bean gum the sizing properties of the locust bean gum were improved markedly. Under the condition of similar grafting ratios, locust bean gum- g-poly(AA-co-methyl acrylate) showed the highest apparent viscosity, water solubility, film strength, wettability, and adhesion to polyester fiber in all the grafted locust bean gum prepared. Meanwhile, locust bean gum- g-poly(AA-co-butyl acrylate) and locust bean gum- g-poly(AA-co-2-ethylhexyl acrylate) had the highest wear resistance and elongation of sizing film, respectively. The modified locust bean gum grafted with acrylate monomers with different carbon chain lengths was able to meet various requirements in the sizing process for polyester yarn.

“…Further to these efforts, other researchers are working on lessening the dependence on land-demanding crops for plastic production by switching to biomass from areas hostile to agriculture [55]. Moreover, carbon sources other than plants (shellfish [56], food waste [57], poultry feathers [58,59], sheep wool [60], etc.) are also successfully being made into fully degradable plastics with highly competitive properties and added values.…”

Bio-Based Plastics Production, Impact and End of Life: A Literature Review and Content Analysis

The accumulation of plastic wastes is one of the most widely spread problems affecting the environment. The reality that plastics can be made from renewable resources and degrade naturally has prompted academics to think outside the box to develop “better for the environment” items. In this paper, a bibliometric analysis of the scholarly publications related to bio-based plastics within the last 20 years is presented. Annual progression, geographic and research area distribution, and keyword co-occurrence were all examined. Six distinct clusters emerged from keyword analysis, which were further categorized into three directions: production to marketing; impact on the environment, economy, and society; and end-of-life (EoL) options. The major focus was on how to counter the weaknesses and challenges of bio-based plastics and take opportunities using the inherent advantages of bio-based plastics. Comprehensive studies regarding the impact of bio-based plastics on the environment, economy and social sustainability are still deficient. Although there are many promising innovations in this area, most of them are at the research stage. The benefits of bio-based plastics and better EoL options can be enjoyed only after increased production.

“…Acetylation, alkylation, and grafting reactions have been performed on both chitin and chitosan . Unfortunately, to the authors' knowledge, only a few studies have dealt with chemical modifications aimed at improving the thermoplastic processing properties . Nevertheless, structural modifications similar to those performed for thermoplastic cellulosics could bring new routes for producing thermoplastic materials and are therefore included in this section.…”

With the objective of a more sustainable circular economy, one long‐term goal is the utilization of renewable resources as feedstock for the production of polymer‐based materials. In order to successfully process such materials using existing industrial‐scale technologies or even recycling processes, the natural polymers must have thermoplastic properties. With only a few exceptions, natural polymers are not thermoplastic. However, chemical and physical modification techniques are able to induce thermoplasticity in natural polymers from biomass resources such as cellulose, lignin, and chitin. Modification techniques focus on masking the hydroxyl groups to disrupt dense hydrogen bonding and so enable polymer chain mobility upon heating. The introduction of long alkyl chains into the polymer backbone effectively improves the thermoplastic processing of natural polymers. With regard to polymer blending, chemical grafting and graft copolymerization are powerful tools for enhancing compatibility. For both chemical and physical modification, solvents such as ionic liquids and deep eutectic solvents are currently being explored for biomass and fiber processing and show promise for the future development of thermoplastic biopolymers. This review describes possible modifications, potential processing difficulties, and gives a summary of relevant studies described in the scientific literature.
