Abstract:
Disclosed herein is a polycarbonate polymer comprising: an isosorbide unit, a polysiloxane unit, and an aliphatic unit different from the isosorbide unit, wherein the isosorbide unit, polysiloxane unit, and aliphatic unit are each carbonate, or a combination of carbonate and ester units, the aliphatic unit different from the isosorbide unit is derived from an aliphatic oligomer having a molecular weight of 900 to 4000, and the calculated bio-content is greater than or equal to 40 weight percent, based on the total weight of the polycarbonate polymer.
