Abstract
Official abstract text for this publication.
Described are a particular group of novel aromatic hydrocarbon telomers that, on bromination, result in the formation of novel flame retardants having a uniquely beneficial combination of properties. The resultant flame retardants and uses thereof are also described. The disclosure includes descriptions of methods for preparing both the aromatic hydrocarbon telomers and the brominated flame retardant polymers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition of the formula: C 6 H 5 CH 2 CH 2 —[(C 6 H 5 )CHCH 2 —] n average CH 2 C 6 H 5 (I) wherein, each C 6 H 5 is a phenyl group, wherein n is an average number in the range of about 2.3 to about 4.8 with the proviso that 1,3-diphenylpropane, a compound of the above formula in which n is 0, optionally is present in said distribution in an amount of not more than 5 GPC area %, and with the further proviso that said distribution optiona…
