METHOD AND DEVICE OF DEPOLYMERISATION Russian patent published in 2009 - IPC C07C67/333 B01J8/08 B01J8/10 C07C4/22 C07C15/46 C07C69/54 C08J11/12 

Abstract RU 2355675 C2

FIELD: chemistry.

SUBSTANCE: invention concerns regeneration of monomer complex ethers of substituted or non-substituted acrylic acid or styrene-containing monomers, particularly device for regeneration of monomer complex ethers of substituted or non-substituted acrylic acid or styrene-containing monomers from polymer material containing respective structural units. Device includes: heated reactor for monomer-containing gas generation from polymer material, and shifting device for propulsion of relocated product, combined with reactor or being a part of reactor. To enhance output and purity of generated monomer, heat carrier comprised by multiple spherical units with diametre within 0.075 to 0.25 mm is preferred.

EFFECT: relocated material containing polymer material and heat carrier.
