Ethylene brassylate: Searching for new comonomers that enhance the ductility and biodegradability of polylactides

Polymer Degradation and Stability, 2017
Abstract Copolymers based on d , l -lactide (D,L-LA) and ethylene brassylate, with EB molar contents ranging from 3 to 39%, were synthesized by ring-opening polymerization at 130 °C using triphenyl bismuth. The poly (D,L-LA-co-EB) presented a random distribution of sequences ( R →1), resulting in a fully amorphous structure with T gS between −17 ...

Effect of molecular weight on the physical properties of poly(ethylene brassylate) homopolymers

Journal of the Mechanical Behavior of Biomedical Materials, 2016
Poly(ethylene brassylate) (PEB) is a biodegradable polyester that nowadays is of particular interest owing to its poly(ε-caprolactone)-like properties (with a Tg at -30°C and a Tm at 70°C) and the low-cost of its monomer. However, it is not simple to achieve high molar masses with conventional catalysts.

Fragrance material review on ethylene brassylate

Food and Chemical Toxicology, 2011
A toxicologic and dermatologic review of ethylene brassylate when used as a fragrance ingredient is presented. Ethylene brassylate is a member of the fragrance structural group macrocyclic lactone and lactide derivatives. The fragrance ingredient described herein is one of 12 structurally diverse C14, C15, and C16 compounds that include (7) saturated ...

Amphiphilic poly(ethylene glycol)-b-poly(ethylene brassylate) copolymers: One-pot synthesis, self-assembly, and controlled drug release

Chinese Chemical Letters, 2015
A set of amphiphilic poly(ethylene glycol)-b-poly(ethylene brassylate) (PEG-b-PEB) copolymers based on the PEB hydrophobic block was first synthesized by ring-opening polymerization of ethylene brassylate with an organic catalyst. The EB/PEG molar ratios and reaction times were adjusted to achieve different chain lengths of PEB.
