Oxytuf® mass polymerized PVC (IIP) contains grafted rubber moieties which provide for excellent impact resistance. The addition of a particulate filler to this resin with preservation of impact properties can be accomplished providing the particles are submicron and can be readily dispersed in the resin. Small particle size, surface treated, precipitated CaCO 3 , when added to IIP provided impact retention superior to that of a homopolymer control containing an added, non‐grafted impact modifier.
