Development of organic glass using Interpenetrating Polymer Networks with enhanced resistance towards scratches and solvents
Abstract
Acrylate polymers are one of common organic glass family. However their sensitivity to
abrasion is an important drawback. Various alternatives were considered but they are often
expensive. In this work, we show that the polymethylmethacrylate (PMMA) glass
resistance can be improved by performing materials based on Interpenetrating Polymer
Network (IPN) at low cost. A series of transparent IPNs based on an aliphatic polycarbonate
and PMMA was synthesized through in situ polymerization process. The formation of two
networks in the IPNs was studied by FTIR spectroscopy. Effects of PMMA cross-linking and
partner proportions in the IPNs were investigated by dynamic mechanical thermal
analysis. Optical properties, solvent and scratch resistances have been also studied.
