Abstract

PURPOSE: To produce a cyclized polymer excellent in abrasion resistance, chemical resistance and adhesiveness, by cyclizing a specified low-MW isoprene polymer to which a maleic anhydride (derivative) has been added.
CONSTITUTION: A modified polymer is obtained by adding 0.3W12mol%, per isoprene monomer unit of polymer, maleic anhydride (derivative) to a low-MW isoprene polymer, cis-1,4-addition content ≤70%, viscosity-average MW10,000W 150,000, obtained by an anionic polymerization method, carrying out an addition reaction of the mixture by heating in the presence or absence of a solvent or a radical catalyst. Next, this modified polymer is dissolved in a solvent so that the concentration is 5W80% and then cyclized at room temperature to 200°C for 2W10hr in the presence of an organic sulfonic acid, a Friedal-Crafts catalyst, etc., so that the iodine value of the cyclized polymer is 100W300.
