STUDYING THE EFFECT OF GLASS ADDITION ON THE PHYSICAL PROPERTIES OF PVC AND PVC/PMMA BLENDS.

Abstract

Thermal analysis techniques were conducted for testing and evaluation of different polymeric samples. Pure samples (such as PVC and PMMA) and composites (with soda-lime glass; powder as filler ) were examined and tested for Tg, thermal expansion and Young modulus (E). Two updating instruments where used for this purpose. Differential scanning calometry (DSC) for pure polymers and thermomechanical analyzer (TMA) for composites. Differential scanning calometry (DSC) testing for sample of polyvinyle chloride (PVC) explain decrease of glass temperature (Tg) from (80.6°C) to (31°C) for the same polymer solved by (THF) solvent and dry it at (100°C). Thermomechanical analysis (TMA) for (PVC/glass) composites appears increase of glass temperature (Tg) with high decrease of Young modulus (E) and transform its mechanical properties from elastic to plastic. Adding the polymer poly mathylemethacrylate to composites (PVC/glass) was lightly effect to glass transition (Tg) and elastic modulus at low ratio of (PMMA) in composite, while the composite (PVC/PMMA/glass) appears elastomer properties when the (PMMA) ratio was 37% in in composite.
