Title:
単環式エステル及びカーボネートの共重合体並びにその製造方法
Document Type and Number:
Japanese Patent JP2004530031
Kind Code:
A
Abstract:
Copolymers having repeating units derived from monocyclic esters or carbonates and certain bicyclic diesters and/or carbonates have controllable rheological properties. The bicyclic diester and/or carbonate copolymerizes easily with the monocyclic monomers, especially with lactide, to form copolymer that can have tailored levels of branching. The copolymers have excellent rheological properties, including increased melt tensions and improved shear thinning, compared to the analogous linear polymers.
