Acrylic impact modifiers for polar thermoplastics such as poly(methyl methacrylate), polyamides, and poly(vinyl chloride) are prepared from emulsion polymer particles with hard methacrylate-rich domains in a continuous polyacrylate network.

Toughened polar thermoplastics

Polyaromatic fibers or microbeads which are swollen with solvent and crosslinked while swollen in such a way that the expanded, or macronet, structure of the swollen fiber or microbead is stabilized and retained even after drying exhibit high surface area and significant adsorptive capacity.

High-surface-area compositions

High-surface-area fiber

Thermoplastic, non-crosslinked polymer compositions having glutaric anhydride units of the formula: ##STR1## wherein R represents CH.sub.3 or H, process for imidizing said compositions, the resultant imide polymers which are free of methyl imide units, and process of devolatilizing an acrylic or methacrylic acid-containing polymer in an extruder to the corresponding anhydride, and then introducing a reactant selected from the group consisting of ammonia, ammonia generators, primary amine, and primary amine generators.

Thermoplastic non-crosslinked polymers, imide polymers, and process for

Disclosed herein are blends of imide containing polymers and vinyl chloride polymers and copolymers.

Blends of imide polymers and vinyl chloride polymers

Polymers containing imide units and a process of imidizing acrylic polymers to any desired degree of imidization without the use of added water or solvent.
