Zusammenfassung:	A process to make a composition that includes a monovinylaromatic polymer and a dispersed phase of polymer made from renewable resources may include forming a polymerizable mixture. The polymerizable mixture may include a monomer or dimer dispersed in a monovinylaromatic monomer, and optionally a rubber dissolved in the monovinylaromatic monomer. The process may include contacting a catalyst with the polymerizable solution at conditions effective to produce a polymer dispersed in the monovinylaromatic monomer. The process may include polymerizing through a radical pathway the solution, optionally in the presence of a free radical initiator and a chain transfer agent, to obtain a monovinylaromatic polymer that includes a dispersed phase. The process may include degassing to separate unpolymerized monomers and comonomers, and recovering a composition of monovinylaromatic polymer.
