    Abstract: Process for the recovery of monomeric styrene from plastic waste ("rubbish") containing styrene polymers by thermal depolymerisation, the rubbish being conveyed in liquid or solid form into a fluidised bed of a solid heat-transfer medium, cracked or depolymerised with an average residence time of less than 60 seconds and recovered from the gaseous cracking products. Preferably, the heat-transfer medium used is magnesium aluminium silicate and the operating gas for maintaining the fluidised bed C1- to C6-hydrocarbons formed during the depolymerisation as a by-product, which are recycled.

    Abstract: Process for the preparation of vinylphosphonic acid derivatives of the general formula I in which R and R can be identical or different and represent hydrogen or a C1-C8-alkyl or C6-C10-aryl or -aralkyl radical which may be substituted by Cl or Br, it being possible for R and R also to be linked to give an alicyclic ring having 3 to 12 ring C atoms, according to which an ethanephosphonic ester of the general formula II in which R and R have the same meaning as R and R but are not a hydrogen atom, X represents a hydroxyl group, a halogen or a radical -OR , in which R is a hydrogen atom or a radical and R is a C1-C6-alkyl radical or an alicyclic ring, is reacted in the gas phase in the presence of solid catalysts.

    Abstract: An aqueous formulation comprises a polymer constructed of from 0 to 99.95% by weight of one or more principal monomers I selected from C 1 -C 20 -alkyl (meth)acrylates, aromatic vinyl compounds having up to 20 carbon atoms, vinyl esters of carboxylic acids containing up to 20 carbon atoms, ethylenically unsaturated nitriles, vinyl ethers of alcohols containing from 1 to 10 carbon atoms and aliphatic hydrocarbons having from 2 to 8 carbon atoms and 1 or 2 double bonds, from 0.05 to 100% by weight of one or more monomers II which carry at least one functional group, which is not to be understood as meaning an ethylenically unsaturated group, this functional group being reactive with the below-defined phosphorus compound in such a way that the phosphorus compound becomes thereby bonded to the polymer, and from 0 to 80% by weight of one or more further monomers III which differ from monomers I and II, and a phosphorus compound which is reactive with the functional group of monomer II, the phosphorus compound being or becoming bonded to the polymer via the functional group. The formulation can be used for consolidating fibrous materials, in particular fibrous webs, or in coatings, impregnants, cleaning or care agents or adhesives to provide flame proofing.
