ABSTRACT:
A haloalkoxylated polybutadiene polymer and a composition containing the polymer which is suitable for use in a flat sheet material such as a roofing membrane is disclosed. The polymer has a superior filler capacity, excellent flame resistivity and acceptable heat aged tensile properties. The composition, which includes at least one polymer of the present invention and from about 5 to about 160 parts by weight of a filler material per 100 parts polymer, is self-adhering without the use of an adhesive and is heat seamable to produce seams which are resistant to temperatures as high as 100.degree. C.
