Polyolefin graft copolymers made with fluorinated monomers

   
   

A fluorine-containing graft copolymer is made from a backbone of an olefin polymer material to which is graft polymerized (a) at least one gaseous fluorinated monomer such as vinylidene fluoride, (b) at least one fluorinated acrylic acid or ester, (c) a mixture of (a) and (b), or (d) a mixture of (a) and/or (b) and a non-fluorinated monomer such as methyl methacrylate. An organic peroxide or a polymeric peroxide is used as the initiator for the graft polymerization process. The graft copolymers have improved surface properties and oxygen barrier properties, and improved thermal stability.

Fluorine-containing сополимер прививка сделан от костяка материала полимера олефина к полимеризованный прививок (a) по крайней мере одному газообразному fluorinated мономеру such as фторид винилидена, (b) по крайней мере один fluorinated акриловые кислота или эстер, (c) смесь (a) и (b), или (d) смеси (a) and/or (b) и нон-non-fluorinated мономера such as метиловый меткрилат. Органическая перекись или полимерная перекись использованы как инициатор для процесса полимерности прививка. Сополимеры прививка улучшали поверхностные свойства и свойства барьера кислорода, и улучшали термально стабилность.
