Tref polymer
PBAT is synthesized from the polymer of 1,4-butanediol and adipic acid and the polymer of dimethyl terephthalate (DMT) with 1,4-butanediol. Adipic acid and 1,4-butanediol are polymerized to create their polyester (plus water). DMT and 1,4-butanediol are also reacted to form their polyester (plus methanol). This polyester is then added to the butylene adipic acid polyester b… WebDownload Table Polymer Samples Used for TREF Runs from publication: High temperature elution peaks in temperature rising elution fractionation (TREF): The behavior of high molecular weight ...
