| Abstract: | Toughened polyvinyl chloride (PVC) with special designed poly( n butyl acrylate) core shell structured latex particles was studied. The impact testing of PVC/core shell blends was used to evaluate the influence of the structure parameters of the core shell particles such as the crosslink density of the rubber core, the particle size and the loading level, the composition and the thickness of the shell polymer layer on the material properties. The results indicate that the particles with a suitable crosslinking degree of the rubber core and a thinner shell were an excellent toughening agent to improve the impact resistance of PVC. |
