Problems solved by technology

The main problem with this composition is that it uses an inhibitor that is continuously consumed and gradually depleted, therefore, the inhibitor must be added continuously or intermittently or at least the proper amount of inhibitor must remain in the system (US 7651635 Column 4, lines 7-13 of the patent)

Abstract

The present invention relates to additive composition for control and inhibition of polymerization of styrene, wherein the composition comprises amine and quinone methide, and wherein the amine is polymerization non-inhibitor amine. In one embodiment, the present invention relates to method of preparation and use of additive composition to control and inhibit polymerization of styrene, wherein the composition comprises amine and quinone methide, and wherein the amine is polymerization non-inhibitor amine. In another embodiment, the present invention relates to additive composition for control and inhibition of polymerization of styrene, wherein the composition comprises oxide treated derivative of amine and quinone methide, and wherein the am ine is polymerization non-inhibitor amine, and to the method of preparation and use thereof.

Description

technical field [0001] This invention relates to an additive composition for controlling and inhibiting the polymerization of monomers, especially styrene. [0002] In one embodiment, the present invention relates to a method for preparing an additive composition for controlling and inhibiting the polymerization of monomers, especially styrene. [0003] In another embodiment, the present invention relates to a method of using an additive composition for controlling and inhibiting the polymerization of monomers, especially styrene. Background technique [0004] Polymerization of monomers, especially styrene, is an operational concern as it leads to the formation of unwanted macromolecules and results in loss of yield of the final product and makes the process uneconomical. [0005] Processes using inhibitors and retarders, and combinations thereof, have been reported to overcome problems with styrene polymerization. [0006] The problem with using inhibitors alone is that t...
