Pressure sensitive adhesive with filler

摘要

A pressure-sensitive adhesive is obtainable by a process comprising polymerizing an ester of acrylic or methacrylic acid having a non-tertiary alcohol comprising 4 to 12 carbon atoms in the alkyl chain (component A) in the presence of at least one kind of a naturally occuring polysaccharide except hydrolyzed starch, cellulose ethers and cellulose esters (component B), radical chain initiators (component C). The pressure sensitive articles manufactured from the pressure sensitive adhesive have improved properties. In particular, the articles are repositionable and the adhesion under humid conditions is improved when cellulose powder is used as component B.
