Zusammenfassung:The present invention discloses a polyvinyl chloride mixture and a preparation method thereof. The mixture comprises the following components in parts be weight: (a) polyvinyl chloride resin of 100 parts and (b) a toughening modifier of 2-20 parts, the toughening modifier being rubber powder whose elongation at break is 1601%-2200% and which contains the percentage of chlorine of 5-45wt%. The elongation at break of the polyvinyl chloride mixture of the present inventions is greatly improved, and the defect of low elongation at break of the polyvinyl chloride product is substantially solved accordingly; therefore, the application scope of polyvinyl chloride surely will be greatly widened.
