Synthesis of Poly(vinyl chloride)-g-Poly(butyl acrylate) Plasticizer via AtomTransfer Radical Polymerization Method

Poly(vinyl chloride) (PVC) is the second most common polymer worldwide due to its low cost andhigh mechanical strength. It is widely used in medical applications, construction materials, andtoys. Many polar chlorine atoms in pure PVC make its chain mobility difficult at room temperature.This problem is solved by using plasticizers and thermal stabilizers. The production of flexible PVCmaterials requires the use of internal softeners. Internal softening provides a solution to theplasticizer migration problem. In this research, poly(butyl acrylate) (PBA) was grafted from PVCusing the atom transfer radical polymerization (ATRP) method with different molar ratios. ThePVC-g-PBA plasticizer increased the flexibility of PVC film as confirmed using tensile analysis.
