Procedure

In the above example, the matrix phase must have about the same R.I. as the grafted rubber phase. The 80 percent by weight of matrix phase must be a blend of SAN and PMMA that matches the graft rubber phase having an R.I. of about 1.5390. A blend of about 42 percent of PMMA and 58 percent of SAN (76/24) was found to have a R.I. about 1.5385 matching the graft copolymer closely, giving a low haze polyblend. The refractive index was determined by an Abbe Refractometer with bromonapthalene as the immersion fluid using ASTM D-2225 at 25° C. The haze values were determined by: ##EQU1##
