The Impact

Abstract The influence of talc and poly (methyl methacrylate) (PMMA)-grafted (g)-talc on the mechanical properties of poly (vinyl chloride) (PVC) was investigated. The graft copolymerization was carried out under nitrogen atmosphere, using the free radical initiation technique. The blend formulations were first dry blended using a mixer before being milled into sheets on a two-roll mill at 165°C, and then hot pressed into composites at 190°C. The flexural modulus of both composites increased with increasing filler content from 0 to 20 part per hundred resin (phr), however the increment of grafted (57.7%) was higher than ungrafted composites (48.5%). A similar trend has also been observed for thermal stability. The impact strength of grafted was increased by 45.82%, whereas 18.96% in reduction was observed for the ungrafted composites. The decrement of flexural strength by 16.6% and 21.1% of grafted and ungrafted, respectively, has also shown the improvement in mechanical properties of grafted composites.

Solution Cast

Microscopical observations of films made up of two incompatible polymers may provide useful insights into the unusual properties of many polymer blends. In the present study an attempt has been made to determine the factors which control the sizes and shapes of the phases present in solution-cast, two-polymer films. The variables included the ratio of the two polymers, the concentration of the solution from which the films were prepared, and the type of solvent used.The polymers studied included poly(vinyl acetate), a copolymer containing 85% poly(vinyl chloride) and 15% poly(vinyl acetate), poly(methyl methacrylate, and polystyrene. These will be abbreviated PVAc, PVC copolymer, PMMA, and PS respectively. The solvents included methyl ethyl ketone (MEK), toluene, benzene, and chloroform and the solution concentrations were varied from 0.2 to 1.0 per cent solids by weight.
