Synthesis of a series of biodegradable poly(butylene carbonate-co-isophthalate) random copolymers derived from CO₂-based comonomers for sustainable packaging

Abstract

Poly(butylene carbonate-co-isophthalate)s (PBCIs) are eco-friendly biodegradable plastics synthesized by using monomers derived from carbon dioxide (CO2).

Copolymers of Functionalized and Nonfunctionalized Polydicyclopentadiene

“…We synthesized four different poly­( f DCPD- stat -DCPD) copolymers with tunable surface hydrophobicity, high hardness, high storage modulus, and excellent thermal stability. Random and statistical copolymers are valued in applications ranging from solar cell devices , and self-healing gels to wind turbine blades and eco-friendly biodegradable packaging . The successful synthesis and characterization of the copolymers described here provides important guidance for the future use of functionalized polydicyclopentadiene copolymers in these various applications, where the increased surface energy (relative to the parent homopolymer) could be harnessed for applying adhesives or coatings.…”

“…Random and statistical copolymers are valued in applications ranging from solar cell devices 24,25 and self-healing gels 26 to wind turbine blades 27 and eco-friendly biodegradable packaging. 28 The successful synthesis and characterization of the copolymers described here provides important guidance for the future use of functionalized polydicyclopentadiene copolymers in these various applications, where the increased surface energy (relative to the parent homopolymer) could be harnessed for applying adhesives or coatings. Moreover, the presence of the ester group, which we have recently shown can be used as a chemical handle for attaching dyes or drug molecules, 14 suggests an additional application for such copolymers in the development of biological materials, for example, multifunctional antibacterial catheters 29 or nanocarriers for drug delivery.…”

Synthesis of degradable and chemically recyclable polymers using 4,4-disubstituted five-membered cyclic ketene hemiacetal ester (CKHE) monomers

“…Degradable polymers nd numerous applications in, e.g., drug delivery, packaging, and agriculture elds. [1][2][3][4][5][6][7][8][9] In the eld of radical polymerization, degradable polymers are prepared via radical ring-opening polymerization of cyclic ketene acetals (CKAs), [10][11][12][13][14] for example, gaining signicant attention. Examples of CKA are 2-methylene-1,3-dioxepane (MDO), [15][16][17][18][19][20][21][22][23] 5,6-benzo-2methylene-1,3-dioxepane (BMDO), [24][25][26] and 2-methylene-4phenyl-1,3-dioxolane (MPDL) [27][28][29][30] (Scheme 1).…”

An Empirical Model for Predicting Biodegradation Profiles of Glycopolymers

“…In the last decade, there has been an increasing recycling trend [ 12 ], which has spread mainly in Europe due to the UE politics towards environment preservation [ 13 ]. Also, new materials with enhanced biodegradable features have emerged as replacements for the classic ones especially in the food industry [ 14 , 15 , 16 ], although it is not enough to diminish the impact that plastic exerts on our environment [ 17 , 18 , 19 ].…”
