Method of making alternating copolymers of isobutylene type monomers |
| abstract |
The present invention comprises the steps of (a) providing a donor monomer composition comprising an isobutylene-type monomer; (b) mixing the donor monomer composition with an ethylenically unsaturated monomer composition comprising at least one ethylenically unsaturated acceptor monomer and substantially free of maleate and fumarate monomers; And (c) polymerizing the mixture resulting from step (b) in the presence of a free radical polymerization initiator. The polymerization takes place in the absence of substantially any Lewis acid and / or transition metal. The isobutylene type monomer is present in a molar excess of at least 10 mole percent, based on the molar concentration of the monomers in the ethylenically unsaturated monomer composition. The ethylenically unsaturated acceptor monomer is present in an amount of at least 15 mole percent of the total monomer composition. |
