Provided is an aliphatic polycarbonate-co-aromatic polyester with long-chain branches. The copolymer includes repeating units represented by -OAO- and Z(O-)a, which are linked via carbonyl (-C(O)-) and -C(O)YC(O)- as linkers. Also provided is an aliphatic copolycarbonate including repeating units represented by -OAO- and Z(O-)a, which are linked via carbonyl (-C(O)-) linkers. The aliphatic copolycarbonate has a weight average molecular weight of 30,000 or more.
