Adhesive agent for application on a sanitary object
Agent for sanitary facilities that can be applied directly on the sanitary object, adheres, and is flushable only after a large number of flushes. The agent includes fillers from the group of surfactants and a bonding agent, wherein the bonding agent is selected from the group of polyalkylene derivatives, hydrogentated polystyrol derivatives, copolymers from the group of monoalkyl esters of poly(methyl vinyl ether/carbonic acid anhydrides, olefin homopolymers, and copolymers of two or more olefins, wherein the olefin homopolymers and copolymers can also be partially hydrogenated, partially oxidized, or further functionalized by graft molecules, and from the group of polyalkyleneimines, including in alkoxylized form, polyetheramines (alkoxylized amines) and polyglycerin polyether alkyl carbonic acids, polymers or derivatives including such polymer groups.

Dilithium initiators
Disclosed herein are highly active dilithio initiators prepared from high molecular weight dienes (C≧6) and methods for the preparation of such compounds. These dilithio initiators result in greater control over polymer microstructure and provide useful polymers and oligomers with low vinyl incorporation.
