Thermal, structural and degradation properties of an aromatic–aliphatic polyester built through ring-opening polymerisation

Abstract

The novel biodegradable aromatic–aliphatic polyester, poly(2-(2-hydroxyethoxy)benzoate), was explored through thermal analysis, X-ray diffraction, dynamic mechanical analysis and comparative bio and catalysed degradation.

Living Coordination Polymerization of a Six‐Five Bicyclic Lactone to Produce Completely Recyclable Polyester

“…Chemically recyclable polymers [1][2][3][4][5][6][7][8][9][10][11][12] have attracted increasing attention in recent years because they allow for recovery of the building block chemicals via depolymerization or creative repurposing through generation of value-added materials,t hus offering af easible solution to the end-of-use issue of polymeric materials and providing ac losed-loop approach towards ac ircular materials economy. [13] However, three key challenges still remain before this approach becomes technologically and economically competitive: energy input, depolymerization selectivity,a nd depolymerizability/performance tradeoff.…”

Catalyst‐Sidearm‐Induced Stereoselectivity Switching in Polymerization of a Racemic Lactone for Stereocomplexed Crystalline Polymer with a Circular Life Cycle

“…Chemically recyclable polymers [1][2][3][4][5][6][7][8][9][10][11][12][13] have lately attracted growing attention because their building block chemicals,o r monomers,c an be recovered for the production of virgin plastics with the same qualities as the original, thus offering af easible solution to the end-of-use issue of polymeric materials and providing ac losed-loop approach towards acircular materials economy. [14] However, there is aparadox between the ability to depolymerize and performance,where polymers that can be readily depolymerized back to monomers often lack physical properties and mechanical strengths to be widely useful, and vice versa.…”

“…Chemically recyclable polymers have lately attracted growing attention because their building block chemicals, or monomers, can be recovered for the production of virgin plastics with the same qualities as the original, thus offering a feasible solution to the end‐of‐use issue of polymeric materials and providing a closed‐loop approach towards a circular materials economy .
