Controlled and Accelerated Hydrolysis of Polylactide (PLA

WebSep 1, 2024 · Furthermore, if the thermoplastic polyester elastomer A has a soft segment content of less than 35% by mass, hydrolysis may be accelerated due to a relatively large hard segment content. That is, the thermoplastic polyester elastomer A has a hard segment content of 20 to 65% by mass and a soft segment content of 35 to 80% by mass. and low ... WebNov 1, 2006 · It was concluded that hydrolysis of the phosphite leads ultimately to the formation of 2,4-di- tert -butyl phenol, phosphorous acid and pentaerythritol, products proposed elsewhere [6]. Regarding the formation of the intermediates, FTIR studies were inconclusive, being limited to the identification of characteristic functional groups. dashboard canvas csusb
