Claim Text:
1. A process to make a composition comprising at least a monovinylaromatic polymer and at least a dispersed phase of one or more polymers made from renewable resources comprising: a) forming a polymerizable mixture comprising: b) contacting a catalyst with the polymerizable mixture at conditions effective to produce a polymer A1 comprising the repeating units (a1) dispersed in the (a2) monovinylaromatic monomer, c) polymerizing through a radical pathway the solution obtained at step b) in the presence of a free radical initiator and in the presence of chain transfer agents, to obtain a monovinylaromatic polymer A2 comprising a dispersed phase of the polymer A1, d) degassing the product of step c) to separate unpolymerized monomers and comonomers and recovering a composition comprising at least the (A2) monovinylaromatic polymer and at least (A1) wherein, the weight proportion A1/(A2+A1) is up to 50%.
