student interning at shoe manufacturer where they use PVC soles. the PVC has and additive butadiene-acrylonitrile and the copolymer goes by the name CHEMIGUM P83. when plain PVC was used for soles, shoes in kitchen environments where there was oil and fat were corroded in a month. when the PVC copolymer was then used, the shoes soles in the kitchen environments lasted for only up to 6 months before corrosion. i have been asked to explain what is the cause of this corrosion of the PVC soles. i was heading in the direction that the fatty acids present on the kitchen floor is causing a reaction with chlorine from the PVC. the chlorine atom is substituting the hyrdroxide molecule on the carbonyl carbon or the hyrdrogen atom on the alpha carbon of the fatty acids. the removal of chlorine from the PVC is breaking down its structure corroding the soles.
Re: why do PVC molds break down in the presence of oils and fats?
