摘要
Commercial polymers are very commonly tailored by plasticization. Plasticization augments plastic elongation and reduces brittleness. It also lowers the processing temperature, reduces sticking in molds, and enhances wetting. Plasticization is achieved by incorporating a plasticizer into polymer matrix, copolymerization, or blending. Among those, adding plasticizer is the most common and simplest way to modify polymer morphology. Plasticizer can lessen the intermolecular forces along the polymer chains. As a result, free volume was increased and Tg was lowered. Therefore, plastics with plasticizer have improved ductility.
