MATERIAL FOR PLASTIC CARDS Russian patent published in 2010 - IPC C08L67/02 C08L33/10 C08L69/00 C08L23/00 C08L91/06 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of polymer composite materials based on polyethylene terephthalate, particularly to making thin-walled articles like plastic cards. The described material contains the following in wt %: polyethylene terephthalate or polyethylene terephthalate based copolymer - up to 100, polymethacrylate as a modifying additive 1-50 and synthetic wax selected from amide, ester, polyethylene wax 0.05-1.5. The material also contains a thermal and a thermo-oxidative decomposition stabiliser, a colouring additive, an olefin polymer or copolymer and a functionalised olefin polymer or copolymer having carboxyl and epoxy groups.

EFFECT: material enables to make articles with better mouldability, impact viscosity of the material increases 2-3 times compared to existing materials.
