Crosslinked polyvinyl acetals

High-molecular, crosslinked polyvinyl butyrals, method for the production and use thereof

Crosslinked polyvinly acetals

Cross-linked polyvinyl acetals

Plasticizer-containing polyvinylbutyrals, method for producing the same and the use thereof, especially for producing films for use in laminated safety glasses

Composition containing polyvinyl acetal with a high content of polyvinyl alcohol units, used for the production of film for use in laminated glass, e.g. for car windscreens

Process for the preparation of mixtures of sorbitol monoesters, sorbitol diesters and partial gycerides

Use of N-(3-dialkylamino) propyl-N-polyhydroxyalkylcarboxamides and their acid adducts as thickeners for liquid aqueous surfactant systems

Use of partly acetalised polyvinyl alcohol polymers as gas hydrate inhibitors, i.e. to prevent the formation and agglomeration of gas hydrates where gas is in contact with an aqueous phase, e.g. in the oil or natural gas industry

Surfactant-containing formulations
