Abstract

  Synthesis of MMA-Co-BA was accomplished at 60"C using benzoyl peroxide as initiator. It is observed that MMA and BA
form copolymers in all monomeric ratios. Tensile properties and hardness were determined for the films prepared from the
blends of chlorinated rubber and MMA-Co-BA. Tensile strength of the films increases as the amount of chlorinated rubber is
increased. The increase in tensile strength might be due to intermolecular and intramolecular rearrangements of copolymer
molecules with chlorinated rubber and an increase in the crosslinking density of the system. The rearrangement of copolymer
molecules with chlorinated rubber also enhanced the elongation at break. The addition of copolymer and plasticizer make the
films more soft and flexible.
