METHOD FOR MODIFYING GRAFT POLYOLEFINS, COMPOSITIONS AND ARTICLES COMPRISING POLYOLEFINS MODIFIED THUS

摘要

Method for the modification of a graft polyolefin with acid or anhydride groups by means of at least partial neutralisation of said groups with at least one neutralising agent, comprising an organic salt (1) which liberates an organic acid (I) on neutralisation, whereby the organic acid (I) from the neutralisation of the graft polyolefin is reacted with at least one inorganic salt (2). The invention further relates to modified polyolefins, (which may be) obtained by the above method, a polymer composition comprising (A) at least one polymer and (B) at least one modified polymer, (which may be) obtained by the above method and an article comprising the modified polyolefin or the composition described above.
