The invention pertains to an improved PVDC composition including certain dienophiles qualified for food contact, which possess an optimized balance of effectiveness in preventing discoloration upon exposure to radiation, with no negative impact on the barrier properties, in particular sorbate esters of formula (I), wherein Ris a C-Chydrocarbon group, preferably a C-Calkyl group, to layers made therefrom, to multi-layer assemblies comprising the same, and to the use of said assemblies for packaging, in particular for packaging foodstuffs. 

Vinylidene chloride polymer composition comprising at least one sorbate ester

The present invention relates to a process for preparing a vinylidene chloride polymer composite comprising a vinylidene chloride polymer and clay materials. The process comprises polymerising vinylidene chloride and clay materials and the resulting vinylidene chloride polymer particle is surrounded by a plurality of clay platelets. The clay materials according to the present invention function as a solid stabilizer in the process for preparing a vinylidene chloride polymer composite of the present invention. The present invention further relates to the vinylidene chloride polymer composite obtainable from the process, to use of the vinylidene chloride polymer composite for the preparation of films, and to films prepared therefrom.

Process for the preparation of a vinylidene chloride polymer/clay composite, films obtained therefrom, and use thereof

Process for the preparation of a vinylidene chloride polymer composite comprising a solid particulate encapsulated in the vinylidene chloride polymer. The process comprises providing a dispersion of a solid particulate material in a liquid phase, said dispersion comprising a RAFT/MADIX agent; providing vinylidene chloride and optionally one or more ethylenically unsaturated monomer copolymerizable therewith to said dispersion; and polymerizing vinylidene chloride and said optionally present one or more ethylenically unsaturated monomer under the control of said RAFT/MADIX agent to form polymer at the surface of said solid particulate material.
