Thermal Analysis of Photopolymerized Polyacrylate thin films

Many times photopolymerization of a formulation mixture does not go all the way to completion. Smaller oligomeric components added to the formulation to aid in mechanical, adhesive and/or thermal properties may not become incorporated into the resulting polymer and may leach out under thermal annealing. We will conduct STA-MS and STA-FTIR experiments on several polyacrylate films and access the extent, if any of oligomer leaching.
