Abstract
In an example, a process of forming a polymeric material is disclosed. The process may include chemically reacting a polyvinyl chloride (PVC) material with a diamine to form a diamine-modified PVC material. The diamine has a chemical formula (CH2)x(NH2)2, where x is not less than 2. The process may also include chemically reacting a halogenated phthalate plasticizer with the diamine-modified PVC material to form a polymeric material having a phthalate plasticizer covalently bonded to a polymer chain.
