PLA copolymerization research more

In recent years, research PLA more Ethyl lactate,  chemical modification, and can be divided into two major categories of physical modification, chemical modification can be prepared by copolymerizing monomers PLA with other polymers, or graft reactive functional group containing a small molecules may also be used other means to reduce PLA crosslinking regularity of molecular chain and crystallinity to increase flexibility and elasticity of PLA; while degradation of PLA can be improved, and mechanical properties of ferrous lactate,  to obtain low-cost products, and thus more Good to meet in the medical field or environmental needs. Compared with chemical modification, physical modification is more convenient, inexpensive, suitable large-scale industrialized.
