Filled thermoplastic resin compositions are provided wherein the filler component is compatible with and does not deleteriously affect the physical properties of the resin. The filler employed is a particulate, solid sphere which can be pre-treated with a surface active agent prior to being incorporated in the resin. The resin composition can also contain other ingredients such as impact modifiers, glass fillers, and the like.
