POLYMER MATERIAL Russian patent published in 2022 - IPC C08J9/00 C08L83/04 C08L67/02 C08L23/06 C08L23/12 D01F8/16 D04H3/05 D04H1/00 B82Y30/00 

FIELD: polymer production.

SUBSTANCE: invention relates to polymer material for manufacturing fiber, film or an absorbing product, fiber, non-woven canvas and an absorbing product that include the specified polymer material, as well as to methods for the formation of polymer material and fiber. Polymer material contains a thermoplastic composition. The composition contains a continuous phase that includes matrix polymer and a siloxane component. The siloxane component contains ultra-high-molecular siloxane polymer that is dispersed in the continuous phase in the form of discrete domains. A porous network is defined in the thermoplastic composition that includes a set of nanopores. Siloxane polymer is characterized in average-weight molecular weight of approximately 100,000 g/mol or more. Matrix polymer includes composite polyester or polyolefin.

EFFECT: obtaining improved polymer material that is porous.
