Abstract
The present invention is polymer blend, which includes at least two immiscible polymers, and a compatibilizer used to produce a substantially homogeneous blend. The compatibilizer is a functionalized nanocomposite which prevents segregation of the polymer components in the polymer blend. The nanocomposites are formed by combining an organoclay and an intercalation agent. The intercalation agent is a reaction product of a polyamine functionalized with an alkyl halide in a polar solvent. The compatibilized blends are used in thin films, which are especially useful in microlithographic applications and as lubricants in low tolerance magnetic disks.
