Abstract
The present invention concerns a monovinylaromatic polymer composition comprising a bio-sourced polymer dispersed phase and optionally a rubber dispersed phase wherein said bio-sourced polymer dispersed phase is predominantly made of particles having a size of less than 10 μm. The present invention also relates to a process (hereunder referred as the first process) to make said monovinylaromatic polymer composition, said process comprising admixing: a monovinylaromatic monomer, at least one bio-sourced polymer, optionally a rubber, at conditions effective to polymerize at least a part of the monovinylaromatic monomer and generate a compatibilizer of the bio-sourced polymer and monovinylaromatic polymer. The present invention also relates to a process (hereunder referred as the second process) to make said monovinylaromatic polymer composition, said process comprising admixing: a monovinylaromatic monomer, functionalized bio-sourced polymer-s), or mixtures of bio-sourced polymer(s) and functionalized bio-sourced polymer(s), optionally a rubber, at conditions effective to polymerize at least a part of the monovinylaromatic monomer. The present invention also relates to a process (her…
