Abstract: New damping (insulating) materials are based on polyvinyl chloride particles or balled up fibers which are extremely lightweight and have a bulk density of 10-200 g/l and a particle weight less than 1 g. The particles are either enveloped by sheets or combined into lightweight components by means of heat or by the addition of binders, such as adhesives, fusion (hot-melt) adhesives, curable polymers, or frothed (pre-foamed), expandable polymers.

Abstract: Polyphenylene ethers, especially poly(2,6-dimethyl-1,4-phenylene) ether, are reacted, in the presence of carboxylic acids, with formaldehyde and hydrogen bromide, whereby 0.02-1 bromomethyl group is introduced, per phenyl nucleus, and a product is obtained containing up to 37.6% by weight of bromine, and losing 2-40% of its weight by thermogravimetric analysis at 250.degree.-325.degree. C. The resultant bromomethylated polyphenylene ethers are suitable, inter alia, as flame retardants.
