POLYMER WELL COMPATIBLE WITH INORGANIC FILLERS

摘要

A modified hydrocarbon polymer obtained by reacting (A) a hydrocarbon polymer having an alkali metal-carbon linkage or an alkaline earth metal-carbon linkage with (B) at least one low-molecular compound having a molecular weight of 2,000 or below which is selected from among low molecular compounds having alkali metal-nitrogen linkages or alkaline earth metal-nitrogen linkages and low-molecular compounds having alkali metal-carbon linkages or alkaline earth metal-carbon linkages and containing amino groups and (C) a multifunctional modifier and having at least one modifying group and a weight-average molecular weight of 10,000 or above, in which the N/c ratio exceeds 1/2 wherein N is the number of moles of nitrogen atoms of the modifying group and c is the number of moles of functional groups of the multifunctional modifier (C); a process for the production of the modified hydrocarbon polymer; and compositions containing the modified hydrocarbon polymer. The invention provides polymers which are improved in the compatibility with inorganic fillers and therefore permit dispersion of inorganic fillers therein in the state of uniform and fine particles.
