FILM APPLIED AS INTERMEDIATE LAYER FOR TRIPLEXES, TRIPLEX CONTAINING THIS FILM AND METHOD OF TRANSPORTATION AND/OR STORAGE OF ROLLED FILM Russian patent published in 2008 - IPC C08J5/18 C08L29/14 B32B17/10 B32B27/08 C08K5/103 

FIELD: inorganic chemistry.

SUBSTANCE: invention concerns film production applied as intermediate layer for triplexes. This film is made of composition containing plasticizer based on partially acetalized polyvinyl alcohols. This invention also covers triplex with at least one glass and specified film adjacent to this glass, and method of transportation and/or storage of rolled film. Task of this invention lies in: production of film characterized by required superior adhesion to glass, as well as reduced self-adhesiveness, i.e. blocking tendency; as well as provision of optimal method of transportation and/or storage of specified film. Assigned task is solved due to the fact that composition used for specified film production contains as an addition agent one or more pentaeritrit ethers of specified structural formula. This addition does not influence film adhesion to glass, however sufficiently reduces self-adhesiveness. Method of transportation and/or storage of rolled film is carried out at temperature at least 20°C. That substantially reduces necessity of film cooling for stacking or rolling-on.

EFFECT: production of film characterized by higher adhesion to glass and reduced self-adhesiveness, that is blocking tendency, production of triplex with this film, as well as provision of optimal method of transportation and/or storage of this film.
