In the first method polystyrene was dissolved in toluene, the rubber was added to the solute and finally nanoclay was added. In the second method nanoclay was added to rubber and the compound was added to polystyrene solution. The study shows that the first method result in better nanofillers dispersion and hence mechanical properties. Keywords: polystyrene,rubber,nanoclay;solventmethod,blending technique. Introduction and Experimental The effect of using both rubber and nanoclay together as the modifier is the topic of this paper.Waste thermocol was used as the polystyrene source. Modification was done by two techniques. Adding rubber and nanoclay together can bring down the amount of rubber required for efficient impact modification[6]. Route1: Waste thermocol is dissolved in toluene[4]. Rubber was added to the solute,after diffusion nanoclay was brought in to a dispersion with toluene and then it was added to the solution. Then the solution was casted into film and cut into small pieces and again mixed and was pressed into sheet and the sculpture was cut from the sheet for testing[3]. Route2: Nanoclay was added to the rubber in a rubber mill and was cut into small pieces and introduced into polystyrene solution. Then the solution was casted into film and the film was cut in to small pieces as before and again mixed and was passed into sheet and the sample were cut from the sheet for testing. The addition of the nano clay concentration change the percentage of the thermocol depends. That means to adding the nanoclay 1 to 5% of the thermocol. To take both method this procedure was use and study the mechanical and thermal property of the polystyrene. The variation of the nanoclay to analyse the property variation of the polystyrene with more sample.Repeate the test in different amount of nanoclay[5].
