A composition of improved strength, stiffness, or toughness consisting essentially of a blend of at least two incompatible thermoplastic polymers, at least one of which has a flexural modulus of less than 150 kpsi, and at least one isocyanate reacting agent having functionality less than three. The composition, an engineering plastic that is impact resistant, is useful as, for example, a molding resin, an automobile bumper or door, or high pressure tubing. |
