ABSTRACT:
A blend of a copolymer of ethylene and at least one other organic monomer X capable of being polymerized to a homopolymer having a glass transition temperature of less than about -20.degree. C. with a homopolymer or copolymer of vinyl chloride, filled with mica, which constitutes about 20-90% of the total weight of the composition, is suitable for the manufacture of noise reduction or vibration damping articles. These compositions are especially suitable for continuous use under harsh environmental conditions, for example, at high temperatures as well as at subzero .degree.C. temperatures.
