Enzymatic Synthesis of Biobased Polyesters and Polyamides
Nowadays, “green” is a hot topic almost everywhere, from retailers to universities to industries; and achieving a green status has become a universal aim. However, polymers are commonly considered not to be “green”, being associated with massive energy consumption and severe pollution problems (for example, the “Plastic Soup”) as a public stereotype. To achieve green polymers, three elements sh...
متن کاملTwo-step biocatalytic route to biobased functional polyesters from omega-carboxy fatty acids and diols.
Biobased omega-carboxy fatty acid monomers 1,18-cis-9-octadecenedioic, 1,22-cis-9-docosenedioic, and 1,18-cis-9,10-epoxy-octadecanedioic acids were synthesized in high conversion yields from oleic, erucic and epoxy stearic acids by whole-cell biotransformations catalyzed by C. tropicalis ATCC20962. Maximum volumetric yields in shake-flasks were 17.3, 14.2, and 19.1 g/L after 48 h conversion for...
متن کاملEnzymatic Synthesis of Renewable 2,5- Bis(hydroxymethyl)furan-Based Polyesters
2,5-Bis(hydroxymethyl)furan (BHMF) is a highly valuable biobased rigid diol resembling aromatic monomers in polyester synthesis. In this work, BHMF is enzymatically polymerized with various diacid ethyl esters by Candida antarctica lipase b (CALB) via a two-stage, three-step method. A series of novel biobased furan polyesters are successfully produced, with number average molecular weights ( ...
متن کاملAn Alternative Method for Synthesis of Thermally Stable Aromatic Polyesters Containing Schiff Base Unites
In this paper, an efficient method for synthesis of aromatic polyesters containing schiff base units is described by preparation of two polyesters. These polyesters have been prepared by the reaction of terephthaloyl dichloride on Schiff bases derived from p-hydroxybenzyldehyde and 4,4-diamino diphenyl ether, 4,4-diamino diphenyl methane. The Polymers were characterized by IR, CHNS, thermal...
