The two phases are mixed and covalently bound to each other via siloxane crosslinks. A method for producing interpenetrating polymer networks. The method comprises providing triglycerides from oils or fats and reacting the triglycerides with a reactive silane to form a silylated triglyceride oil. The silylated triglyceride oil and a silanol terminated polysiloxane are emulsified with water in a predetermined ratio. Thereafter, crosslinking agents are added and the water is removed from the emulsions providing siloxane crosslinks between the two intimately mixed immiscible phases. ## Claims ### Claim 1 A composition of matter comprising an interpenetrating polymer network of a combination of a silanol-containing polylsiloxane phase and a silylated triglyceride oil phase, wherein the two phases are mixed and covalently bound to each other. ### Claim 2 (depends on 1) A method of for producing interpenetrating polymer networks said interpenetrating polymer networks as claimed in claim 1, said method comprising: a. providing triglycerides from oils or fats;
