Abstract: This disclosure relates to viscoelastic damping materials and constructions which may demonstrate low temperature performance and adhesion and which may be used in making vibration damping composites. Viscoelastic damping materials and constructions may include polymers or copolymers of monomers according to formula (I): CH 2═CHR1—COOR2 wherein R1 is H, CH3 or CH2CH3 and R2 is a branched alkyl group containing 12 to 32 carbon atoms.
