Deep Dive into Plastic Monomers, Additives, and Processing Aids

Additives, Monomers, Plastics, Polymers, Toxicity Abstract A variety of chemical substances used in plastic production may be released throughout the entire life cycle of the plastic, posing risks to human health, the environment, and recycling systems. Only a limited number of these substances have been widely studied.

Toughening modification of poly(butylene terephthalate)/poly(ethylene

Along with the increase of POE-g-GMA, the values of T g shift from 79.3 to 82.1 ¡ãC, and the tan ¦Ä decreases from 0.29 to 0.25, which were caused by the chain-extending reaction and micro-crosslink reaction occurred between POE-g-GMA and PBT/PET matrix. The initial increase of T g can be attributed to the chain-extending reaction between epoxy

Low Molecular Weight and Polymeric Modifiers as Toughening Agents in

The inherent brittleness of poly(3-hydroxybutyrate) (PHB) prevents its use as a substitute of petroleum-based polymers. Low molecular weight plasticizers, such as tributyl 2-acetyl citrate (TAC), cannot properly solve this issue. Herein, PHB films were obtained using a biosynthesized poly(3-hydroxyoctanoate) (PHO) and a commercially available TAC as toughening agents. The use of TAC strongly

An environmentally sustainable plasticizer toughened polylactide

Introduction. Polylactide (PLA), a most popular green plastic, provides a promising alternative to polymers derived from petroleum, and attracts much interest. 1¨C3 Because of its renewability, biodegradability, biocompatibility and competitive physical properties, PLA has thus been applied in biomedical materials, packaging, and the automotive industry.

The T g of the PLA/CD blend dropped significantly with increasing CD content, most likely demonstrating good plasticizing efficiency with PLA. For instance, the T g value of PLA decreased by 43 ¡ãC and 17 ¡ãC for PLA/CD-10 and PLA/CD-20, respectively. As the content of CD was increased to 20 wt%, the T g peak became very broad and nearly

Mechanisms for combining polyamide and epoxy and their effects on

Polyamide is of particular interest as a thermoplastic toughening agent due to its potential to form covalent chemical bonds with EP. Further, both PA and EP are polar molecules. This compatibility enhances their miscibility, promoting interdiffusion to allow for mechanical as well as chemical crosslinking. 1 Polyamides are polymers in which monomers are linked with amide bonds.
