文摘
- •
Controllability of ring opening polymerization of L-lactide and amino bearing functional cyclic carbonate was greatly improved by organocatalysis.
- •
Gradient poly(ester-carbonate)s was formed during the copolymerization.
- •
Free amino groups was achieved by deprotection in acidic environment.
- •
Poly(γ-benzyl-l-glutamate) (PBLG) was introduced to the amino bearing macro-initiators via “graft from” method with high control.
