Polymer blend clarity |
| abstract |
Optical clarity is improved in blends of two transparent immiscible polymers by addition of a third polymer which is selectively miscible with one of the two original immiscible polymers. The ratio of amounts of the third polymer and the one original polymer with which it is miscible is adjusted to achieve a resultant refractive index close to the refractive index of the other of the two original immiscible polymers. Alternatively, if particular amounts of the third polymer and the original polymer with which it is miscible are desired, then the other of the two immiscible polymers is chosen to be one having a refractive index close to the resultant refractive index of the two miscible polymers. One particular blend system in which optical clarity is improved by use of the methods of this invention is a blend comprising: (a) a resinous monovinyl aromatic-conjugated diene copolymer; (b) a styrene-maleic anhydride copolymer; and (c) poly(alpha-methylstyrene). |
