With the initial focus on the unintended impact of dynamic covalent linkages on the viscoelasticity of commercial rubbers, efforts in modern times have transitioned into designing dynamic covalent polymer networks with unique adaptive properties. Whereas self-healing and thermoset...

Convenient synthetic approach to poly(N‐Methyl L‐alanine) through polycondensation of...

This study describes a convenient and phosgene-free synthesis of poly(N-methyl L-alanine) with solubility in water using polycondensation of activated urethane derivative of N-methyl L-alanine was described. The polycondensation of activated urethane derivative was heated at 60 DEGC with n-butylamine as an initiator to give the corresponding...

Hydrogen bonds prevent obtaining high molar mass PHUs

Poly(hydroxyurethane)s (PHUs) are desired to replace PolyUrethanes (PUs) which are synthesized using harmful isocyanates. Nevertheless, the synthesis of PHUs starting from cyclocarbonates and amines displays two major drawbacks: the low reactivity observed during the opening of (poly)cyclocarbonates by (poly)amines and the low molar masses of...

Compressive shape memory behavior of spring‐shaped polylactic acid alloy type

This article presents an experimental study on the shape memory behavior of blends of thermoplastic polyurethane (TPU) and biodegradable polylactic acid (PLA) at the PLA/TPU weight ratios of 70/30 (PT7030) and 50/50 (PT5050). The manufactured springs were studied comprehensively based on their morphological and thermal properties. Scanning electron...
