Modifying a polyolefin containing acid or anhydride groups, useful as compatibility or dispersion agents for other polymers or fillers, where acid released by neutralization is reacted with inorganic salt

摘要

Method for modifying a polyolefin (A), grafted with acid or anhydride groups, by at least partial neutralization of these groups using as at least one neutralizing agent (B) an organic salt that releases an organic acid (I) during neutralization. The new feature is that the (I) formed is reacted with at least one inorganic salt (C). Independent claims are also included for the following: (1) modified (A) prepared by the new process: (2) composition containing at least one polymer (D) and at least one modified (A); and (3) article comprising the composition of (2) or a modified (A) obtained by the new method.
