METHODOLOGY OF INITIATION OF PORE FORMATION Russian patent published in 2017 - IPC C08J9/00 C08J5/18 D01F6/00 B82Y30/00 C08L23/00 C08L67/04 B32B27/04 

FIELD: technological processes.

SUBSTANCE: invention provides a technique (method) for initiating the formation of pores in a polymeric material that contains a thermoplastic composition. The thermoplastic composition contains microinclusions and nanoinclusions, dispersed in a continuous phase, which includes a matrix polymer. To initiate pore formation, the polymeric material is subjected to mechanical stretching (for example, bending, stretching, twisting, etc.) to impart energy to the continuous phase interface and inclusion additives, which enables separation of the inclusion additives from the interface to create a porous network. The material is also pulled in a solid state in the sense that it is maintained at a temperature below the melting point of the matrix polymer.

EFFECT: xxxxxxx.
