A polymer, which is a composition of a battery, includes a polyester. The polyester is polymerized by at least two monomers, wherein each of the at least two monomers is selected from a group consisting of a carbonate ester and a polyol. The polyester can further include an end-capped polycarbonate ester, and the end-capped polycarbonate ester includes an inert group on an end thereof.

Provided is an aliphatic polycarbonate macropolyol including OAO and Z(O).sub.a as repeating units. In the aliphatic polycarbonate macropolyol, the repeating units OAO and Z(O).sub.a are linked to each other via carbonyl (C(O)) linkers or are bonded to hydrogen to form terminal OH groups. The number of moles of the terminal OH groups is from aZ to aZ+0.2Z (where Z represents the number of moles of the repeating unit Z(O).sub.a). Further provided is an aliphatic polycarbonate-co-aromatic polyester macropolyol including OAO and Z(O).sub.a as repeating units. In the aliphatic polycarbonate-co-aromatic polyester macropolyol, the repeating units OAO and Z(O).sub.a are linked via carbonyl (C(O)) and C(O)YC(O) as linkers or are bonded to hydrogen to form terminal OH groups.

A polymer includes a hyper-branched polyfunctional (meth)acrylate and having a polycarbonate backbone, wherein the polymer is a liquid at 25 C.
