Abstract: The present invention relates to a method of storing a biocatalyst, which biocatalyst is capable of converting acrylonitrile to acrylamide, comprising the steps: (a) providing an aqueous suspension comprising the biocatalyst, which is capable of converting acrylonitrile to acrylamide, which aqueous suspension is an aqueous fermentation broth; (b) sequentially in either order or simultaneously (b) concentrating the aqueous suspension comprising the biocatalyst to a concentration of at least 3% (w/w); and (b2) reducing the temperature of the aqueous suspension comprising the biocatalyst to a temperature of below 8° C., thereby forming a concentrated aqueous suspension; and (c) maintaining the concentrated aqueous suspension of step (b) at a temperature of below 8° C. The invention also relates to a biocatalyst composition obtainable by this method and also the use of the biocatalyst composition in a process of preparing (meth-) acrylamide aqueous solution from (meth-) acrylonitrile. The invention further relates to a method for producing an aqueous (meth-) acrylamide solution comprising the aforementioned storage method and also to a method for producing polyacrylamide comprising the aforementioned storage method.

Abstract: What are described are copolymers formed from (a) at least one monomer M1 of the formula in which R1 is an organic radical having a (meth)acryloyl group, R2, R3 and R4 are each independently a hydrogen atom or a C1- to C10-alkyl group; and (b) at least one ethylenically unsaturated, free-radically copolymerizable monomer M2 other than the monomers M1. What are also described are two-pack adhesives comprising the copolymers and a polyfunctional hardener. The copolymers and the two-pack adhesives can be used as laminating adhesives.
