Determining basic thermodynamic properties for some poly(n-alkyl methacrylates)

摘要

Polymethacrylates have been known to belong to an intermediate class of materials between commodity and engineering plastics. Those materials are used mainly for glass and molding compounds, and also for dispersions, adhesives, additives, and binders.1 In addition, block copolymers from polymethacrylates and polystyrene are widely used as passive electronic materials and as templates.2–4 Therefore, there is a need for studying the bulk thermodynamic properties of those polymethacrylates and also the phase behavior of block copolymers from them. Basic thermodynamic data such as volumetric properties for the methacrylate polymers are then essential to suffice the need. Once the volume data for given polymeric materials are given, other thermodynamic properties of the materials can be obtained by various thermodynamic relations.
