Patent ID: 10494525

Abstract:
The composition can include a polyamide, hollow glass microspheres having amino groups on at least a portion of their surfaces, and an impact modifier comprising at least one of polyolefin units or polydiene units and at least one of carboxylic acid or carboxylic acid anhydride functional groups. The composition can include a matrix of a polyamide modified with an impact modifier comprising at least one of polyolefin units or polydiene units and hollow glass microspheres dispersed in the matrix. At least some of the impact modifier and the polyamide share at least one of an amide bond, an imide bond, or a carboxyl-amine non-covalent bond, and at least some of the hollow glass microspheres and the matrix share at least one of an amide bond, an imide bond, or a carboxyl-amine noncovalent bond. The impact modifier is present in an amount of at least about 5 weight percent.
