PMMA has good compatibility with PVC due to specific interaction of a hydrogen bonding type between carbonyl groups (C=O) of PMMA and hydrogen from (CHCl) groups of PVC (Belhaneche-Bensemra et al.， 2002; Ramesh et al.， 2002). Zhou et al... PMMA has good compatibility with PVC due to specific
interaction of a hydrogen bonding type between carbonyl
groups (C=O) of PMMA and hydrogen from (CHCl) groups
of PVC (Belhaneche-Bensemra et al.， 2002; Ramesh et al.，
2002). Zhou et al. (2001) studied the relationship between
the coating thickness of PMMA on the surface of talc and
mechanical properties of PMMA-g-talc/PVC composites，
and found that there existed a critical thickness. Xie (2001)
found that the PMMA coating on talc improved the dispersion
of talc in the PVC matrix and enhanced the interfacial
adhesion between talc and PVC. There appears to be a
critical coating thickness of PMMA on the talc surface for
optimum toughening. Quan et al. (2002) reported improved
toughness and intension of the PVC composites filled with
CaCO3/ACR core-shell complex particles prepared by
in-situ emulsion polymerization of acrylic ester.
In the present work， PMMA coated on the surface of
CaCO3 nanoparticles by in-situ emulsion polymerization
was characterized by FT-IR and 1H-NMR. The effects of
PMMA thickness and particle fraction on the mechanical
properties of PMMA-coated CaCO3 /PVC nanocomposites
were also investigated.
