VIBRATION DAMPED SANDWICH SYSTEMS HAVING INTERLAYERS OF COPOLYMERS OF ETHYLENE AND MIXTURES OF ISONONANE-, ISODECANE AND ISOUNDECANE-CARBOXYLIC ACID VINYLESTERS

摘要

Vibration damped sandwich systems having an improved damping effect within a broad range of temperature and consisting of hard plates and a vibration damping interlayer, said interlayer comprising a copolymer of ethylene with a mixture of isononane-, isodecane- and isoundecane-carboxylic acid vinyl esters and acrylic and/or methacrylic acid.
