IMPROVED STRUCTURES MADE OUT OF POLYMERS PRODUCED WITH USE OF CATALYTIC AGENTS WITH ONE ACTIVE CORE Russian patent published in 2005 - IPC

FIELD: production of packing structures made out of polymeric materials.

SUBSTANCE: the invention is dealt with improved packing structures made out of polymeric materials in the form of the compressing containers. The compressing distributing container made in the form of a pipe contains a head having a distributing hole and a ledge, and a wall of a body containing the first ethylene polymer in the form of a pipe. The wall of the body and the head are linked by a layer containing the first ethylene polymer. At that the head contains a mix of propylene polymer and the second ethylene polymer produced by polymerization with application of the catalytic agent with one active core, such as a metallocene. The compressing distributing container is capable according to the invention to withstand the considerable pressure tensions without flawing. The invention also presents a method, that allows to strengthen binding between the head and the layer of the body wall of the compressing distributing container.

EFFECT: the compressing distributing container is capable to withstand the considerable pressure tensions without flawing.
