Flame retardant

Disclosed is a polymer foam with density in the range from 5 to 120 kg/mcomposed of a polymer component including at least one styrene polymer and from 0.1 to 5 parts by weight of a flame retardant mixture including at least one phosphorus compound of the formula PRRR. A process for producing the polymer is also disclosed.

Halogen-free, phosphorus-containing flame-retardant polymer foams

The present invention relates to initiators of the general formula {[M(L)]X}, wherein said initiators preferably have (SbF) as a counterion and are obtainable by a complexing reaction of a corresponding metal-SbFsalt with a corresponding ligand (L). The present invention further relates to preparations and epoxy resin systems that contain such initiators and, in particular, are non-thermally and/or thermally curable.

Metal compounds for use as initiators

The use of 1,3-substituted imidazolium salts of the formula I in which

Catalyst for curing epoxides

The invention relates to general syntheses of (6H)-dibenz[c,e] [1,2]-oxaphosphorins which are substituted with nitrogen compounds on the phosphorus atom and comprising commercially available 6H-dibenz[c,e] [1,2]-oxaphosphorin-6-oxides. These nitrogen-containing (6H)-dibenz[c,e] [1,2]-oxaphosphorins can be used as reactive starting substances for further syntheses or as flameproofing agents or as stabilisers.

Method for the production of dibenz[c,e] [1,2]-oxaphosphorin derivatives, amino-dibenz[c,e] [1,2]-oxaphosphorin and also use thereof

A process is provided for the preparation of 9,10-dihydro-9-oxa-10-organyloxyphosphaphenanthrene-10-oxide or -thione and derivatives of same substituted on the phenyl groups, in which: (a) 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOP) or a derivative of same is reacted in the presence of at least one mono- or polyhydric alcohol with at least one ortho ester with formation of a first intermediate product, (b) the intermediate product from step (a) is optionally reacted with at least one further mono- or polyhydric alcohol with formation of a further intermediate product and (c) the intermediate product from steps (a) or (b) is transformed by addition of oxidation agent into 9,10-dihydro-9-oxa-10-organyloxyphosphaphenanthrene-10-oxide or -thione or a derivative of same substituted on the phenyl groups.

Process for the preparation of 9, 10-dihydro-9-OXA-10-organyloxyphosphaphenanthrene-10-oxide or -thione and derivatives of the same substituted on the phenyl groups

A process is provided for the preparation of 9,10-dihydro-9-oxa-10-organylphosphaphenanthrene-10-oxide and derivatives of same substituted on the phenyl groups, in which: (a) 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOP) or a derivative of same is reacted in the presence of at least one mono- or polyhydric alcohol with at least one ortho ester with formation of a first intermediate product, (b) the intermediate product from step (a) is optionally reacted with at least one further mono- or polyhydric alcohol with formation of a further intermediate product and (c) the intermediate product from steps (a) or (b) is transformed by addition of catalytic quantities of alkylation agent into 9,10-dihydro-9-oxa-10-organylphosphaphenanthrene-10-oxide or a derivative of same substituted on the phenyl groups.

Process for the preparation of 9,10-dihydro-9-oxa-10-organylphosphaphenanthrene-10-oxide and derivatives of the same substituted on the phenyl groups

The present invention relates to a process for preparing 6-alkoxy-(6H)-dibenzo[c,e][1,2]oxaphosphorins, wherein 6H-dibenzo[c,e][1,2]oxaphosphorin 6-oxides of the formula I are used as the reactant.
