Most polymers suffer from certain problems during processing such as energy consumption and low flow rate. In addition, the polymeric products do not degrade easily in natural environment after being used. To overcome these problems polymeric material can be blended with other polymers that have the ability to improve the processability and biodegradation. This book contains: the preparation of four novel hyperbranched polyester polymers (HBPEs), by the preparation of the starting material B3 monomer and then mixing it with the four other types of materials as A2 monomer, using the...
