THE BASIC PRINCIPLES OF WHAT IS PVA

Subsequently, the PVAc undergoes a approach known as alcoholysis (or hydrolysis) while in the presence of an Liquor and a strong base or acid catalyst. The acetate teams during the PVAc are replaced by hydroxyl groups, leading to the development of PVA.Nevertheless, hydroxyl groups in PVA can slow the biodegradation rate, as they can interact with
