Reaction Mechanism on the Modification of PLA by Melamine via DMP

Abstract:

When poly (lactic acid-co-melamine) [P(LA-co-MA)] is synthesized via direct melt polycondensation (DMP), with the more MA in the feed content, the copolymer with a three-MA-core structure linked by the ether bond is formed. Increasing the molar feed ratio n(LA)/n(MA), the structure of the copolymers is gradually changed from multi-core structure into SPLA structure only containing one MA core, and a peak value of M_w exists as expected. The aromatic cores with different functional groups have an important influence on the M_w peak value, and the internal factors are the conjugate effect and the nucleophilicity caused by the different functional groups themselves.
