Silicone surfactants for use in polyurethane foams prepared using natural oils based polyols comprise silicone copolymers possessing alkyl and polyalkylene oxide polyether pendants. The silicone surfactants yield foams having improved physical properties as compared to other surfactant compositions when used in vegetable oil based urethane foams.

Silicone surfactant for use in polyurethane foams prepared using vegetable oil based polyols

A process is disclosed for producing silicone copolymers, wherein the process comprises the steps of:

Continuous manufacture of silicone copolymers via multi-stage blade-mixed plug flow tubular reactor

A continuous process for the manufacture of silicone copolymer utilizing at least one static mixing plug flow reactor, and optionally two static mixing plug flow reactors in a series or parallel. Silicone copolymers produced in accordance thereof are substantially free of unreacted hydrogen siloxane starting material and may be used without further purification. The static mixing plug flow reactor contains static mixing elements capable of creating eddies and vortices of sufficient intensity that a biphasic liquid mixture such as a hydrogen siloxane fluid and an polyether olefinic reactant, undergoes shearing of the droplets of each material so that one phase disperses into another to provide intimate contact between the two phases to allow the reaction to proceed.
