Abstract
AbstractThe influence of the length of side groups on the thermomechanical behavior of poly‐(ethylene glycol methacrylate), poly(diethylene glycol methacrylate), and their copolymers was studied. It was found that the hydroxyl endgroups increase the viseosity of these polymers compared to poly(propyl methacrylate) and poly(hexyl methacrylate); the increasing length of the side chains lowers the differences between the mechanical behavior of the poly(alkyl methacrylates) and poly(glycol methacrylates). The thermomechanical curves are sufficiently sensitive to determination of the fundamental mechanical characteristies of network polymers with very small differences of network density. A relation was obtained between the physical degree of crosslinking of poly‐(ethylene glycol methacrylate) and poly(diethylene glycol methacrylate) and the content of the crosslinking agent based on thermomechanical measurements, and the assumption has been expressed, that the physical degree of crosslinking can be partly influenced by the supermolecular structure of the polymers.
