Abstract
Novel linear polysiloxane-polylactone block copolymers are useful as surface modifying additives due in part to their miscibility with a wide variety of base polymers. A particularly preferred polysiloxane-polycaprolactone linear blocked copolymer is miscible with nylon and is useful for forming surface modified nylon products.
