摘要:
A description is given of the use of a polymer dispersion for preparing sound deadener compositions, the polymer dispersion being obtainable by emulsion polymerization of free-radically polymerizable monomers in the presence of at least one protective colloid which is an amphiphilic graft copolymer. Preferred protective colloids have a polyalkylene oxide main chain and vinyl ester-comprising side chains. A description is also given of corresponding sound deadener compositions which comprise the polymer dispersion, and of a method for damping oscillations or vibrations of vehicle components.
摘要:
The present invention relates to the use, for stabilizing polymers, in particular polyolefins, with respect to exposure to UV radiation, of fine-particle polymer powders comprising at least one UV absorber. The present invention further relates to stabilizer mixtures for stabilizing polymers with respect to exposure to UV radiation, oxygen and heat, which, inter alia, comprise these polymer powders, and to a process for stabilizing polymers, in particular polyolefins, with respect to exposure to UV radiation, oxygen and heat, which comprises adding, to the polymers, in particular to the polyolefins, an effective amount of these stabilizers. The present invention further relates to polymers, in particular polyolefins, which have been stabilized with respect to exposure to UV radiation or with respect to exposure to UV radiation, oxygen and heat, which comprise an effective amount of these polymer powders or, respectively, stabilizer mixtures, and to articles produced from these stabilized polymers, in particular polyolefins.
