  • Impact modified thermoplastic composition
    Patent number: 10011673
    Abstract: The present invention relates to thermoplastic compositions comprising as impact modifier a rubber containing graft polymer prepared by the process of emulsion polymerization and recovered by a special process controlling and adjusting the pH value, the use of the thermoplastic compositions in the production of molded bodies, and to the molded, bodies themselves. The present invention relates also to thermoplastic compositions comprising a polymeric impact modifier with a core-shell structure made by a multistage process and recovered by a special process controlling and adjusting the pH value comprising at least one gradient polymer the use of the thermoplastic compositions in the production of molded bodies, and to the molded, bodies themselves.

  • IMPACT MODIFIED THERMOPLASTIC COMPOSITION WITH HYDROLYTIC SENSITIVITY TO OBTAIN HIGHER FLUIDITY WHILE KEEPING HIGH IMPACT STRENGTH
    Publication number: 20120157628
    Abstract: The present invention relates to, amongst other things, a process for manufacturing an impact modifier, concerns impact modified thermoplastic molding compositions and in particular a process for manufacturing and recovering the impact modifiers and their use in polymeric thermoplastic compositions. More particularly the present invention relates to a polymeric impact modifier with a core-shell structure manufactured by a multistage process comprising a special recovery process so that the composition of the thermoplastic polymer containing the impact modifier has a high fluidity while keeping its high impact strength.
