Preparation and investigation of brominated poly-4-methyl-1-pentene as target material

This paper presents the preparation of patially brominated poly-4-methyl-1-pentene(PMP).The composition and stucture of patially brominated PMP are studied by means of element analysis，IR and TGA. Br atom was found to be substituated easily with H atom of PMP to form the chemical doped polymers．The polymer will be stabilized below 150℃and lose the HBr up to 150℃. The well doped low density material was made by this means.
