Distinctive Polymorphism-like Isodimorphism in Poly(propylene succinate-ran-propylene fumarate)
文献摘要：
Co-crystallization of different monomeric units fundamentally contributes to the versatile and tunable performance of random copolymers.At present,the crystallization manners of random binary copolymers have been divided into three categories:isomorphism,isodimorphism and comonomer exclusion.Each category,however,has its own advantages and disadvantages.Therefore,it is challenging to design and prepare random copolymer sharing the advantages of isomorphism and isodimorphism through a new co-crystallization manner beyond the ones already exist.On the basis of previous study on poly(alkylene succinate-ran-alkylene fumarate)whose co-crystallization can be extensively and finely regulated by simply varying the chemical structure of alkylene,random copolymers of poly(propylene succinate-ran-propylene fumarate)(PPSF)are synthesized using 1,3-propanediol as the diol source.The thermal properties and crystal structure of PPSF are investigated,and,intriguingly,it is proved that PPSF is an isodimorphism system while displays similar composition-dependent thermal properties and crystallinity as isomorphism.That is,PPSF exhibits a novel co-crystallization behavior that has rarely been discovered,which would combine the advantages of both isomorphism and isodimorphism.Consequently,PPSF could be termed as a new-type,special composition-dependent polymorphism.Besides,the altering of PPS-like to PPF-like crystal structure of PPSF when changing chain composition has been proved to originate from the shift of dominant inter-segment interaction from van derWaals forces to strong hydrogen-bonding interaction.This work enriches the co-crystallization manner of random copolymers,leading to more diverse performance design of polymer materials.
