Abstract:
A resin having an improved powder characteristics and useful as an impact modifier for vinyl chloride resins, which comprises an MBS resin satisfying the following relational equations (1) and (2):âˆ’1.5x+140&lE;y&lE;âˆ’1.65x+180â€ƒâ€ƒ(1) 55&lE;x&lE;70â€ƒâ€ƒ(2) wherein x is a butadiene content (% by weight) in the MBS resin, and y is a Vicat softening point (Â°C.) of the MBS resin, and 0.1 to 10 parts by weight of a hard polymer per 100 parts by weight of said MBS resin, and which is obtained by coagulating a latex of said MBS resin, adding said hard polymer in the state of latex or coagulated slurry to the resulting coagulated slurry of MBS resin, and recovering the powder from the resulting mixture.
