ANALYSIS OF DEPENDENCE OF THE FLOW TEMPERATURE OF THE PLASTICIZED POLYMER ON THE CHEMICAL STRUCTURE AND CONCENTRATION OF THE POLYMER AND THE PLASTICIZER
Polymeric materials are widely used in construction. The properties of polymeric construction materials vary to a substantial extent; their durability, thermal stability, frost resistance, waterproof and dielectric properties are particularly pronounced. Their properties serve as the drivers of the high market demand for these products. These materials are applied as fi nishing materials, molded sanitary engineering products and effective thermal insulation and water proofi ng materials.
The authors analyze the infl uence of the chemical structure and structural features of poly-mers on their properties. The authors consider fl ow and vitrifi cation temperatures of polymers. These temperatures determine the parameters of polymeric products, including those important for the construction process.
The analysis of infl uence of concentration of the plasticizer on the vitrifi cation temperature is based on the two basic theories. In accordance with the fi rst one, reduction of the vitrifi cation tem-perature is proportionate to the molar fraction of the injected plasticizer. According to the second concept, reduction of the vitrifi cation temperature is proportionate to the volume fraction of the in-jected solvent. Dependencies of the fl ow temperature on the molecular weight and the molar fraction of the plasticizer are derived for PVC. As an example, two plasticizers were considered, including dibutyl sebacate and dioctylftalatalate. The basic parameters of all mixtures were calculated through the employment of “Cascade” software programme (A.N. Nesmeyanov Institute of Organoelemental Connections, Russian Academy of Sciences).
Key words: polymeric construction materials, vitrifi cation temperature, fl ow temperature, polymer molecular mass, plasticizer.
