ABSTRACT:
Thermoplastic core-shell compositions having a rigid core, a rubbery acrylic shell and transition layer intermediate between the core and shell layers and formed of the core and shell monomer components have excellent elastomeric properties. Although the rigid and rubbery components include interreactive functional monomers, the resulting elastomers remain thermally processable in extrusion and injection molding equipment.
