ABSTRACT:
Immobilized Lewis acid catalysts comprising a polymer having at least one Lewis acid immobilized within the polymer structure, said polymer having the monomer units represented by the structural formula: ##STR1## where D is OR', NH.sub.2, NHR', OM' or OM"; E is at least one Lewis acid residue, R is an alkyl group or cycloalkyl group; R.sup.2 is a divalent hydrocarbyl group, R' is an alkyl, cycloalkyl, aryl or alkylaryl group, M' is an alkali metal and M" is an alkaline earth metal. The immobilized Lewis acid catalyst is useful in olefin polymerization and in alkylation or aromatic or isoparrafinic hydrocarbons with an olefin.
