A duromer, a method for producing the duromer, a use of the duromer as well as a flame retardant containing the duromer and plastics compositions thereof are disclosed. A phosphorous-containing polymer which is based on multi-functional esters of unsaturated carboxylic acids is three-dimensionally cross-linked and forms the claimed duromer as described. The duromer is suitable as a flame retardant and suitable for use in flame retardants for plastics.

Duromer, production method, use and compositions

Nitrous bridged derivatives of 6H-dibenz[c,e][1,2]-oxaphosphorine-6-oxides, process for the preparation and use thereof. The invention refers to nitrous bridged derivatives of 6H-dibenz[c,e][1,2]-oxaphosphorine-6-oxides, a process for the preparation thereof and their use as flameproofing agents for polymers such as polyesters, polyamides, polycarbonates, polystyrenes, polyethylene, polypropylene, phenolic and epoxy resins. The derivatives have the Formulae I or II: 

Nitrous bridged derivatives of 6H-dibenz[c,e][1,2]-oxaphosphorine-6-oxides, process for the preparation and use thereof

The invention relates to a method for preparing halogen-free flameproof epoxy resins, in which a halogen-free epoxy resin is reacted with a polyfunctional aldehyde or ketone and a phosphinic acid derivative, wherein the phosphinic acid derivative contains at least one P&#x2014;H-active structural unit of the formula &#x2550;PH(O) and is used in an amount equivalent to the polyfunctionality of the aldehyde or ketone, to a halogen-free flameproof epoxy resin obtainable by this method, to the use of the epoxy resin as a base material for the manufacture of printed circuit boards and printed circuits and to intermediates used to prepare the epoxy resins.

Halogen-free flameproof epoxy resin formulations

Combination compounds from curing agents/accelerators and flame-protection agents for the latent curing/acceleration of epoxide resin systems and their endowment with flame-retarding properties, the epoxide resin systems being able to be thermally cured, as well as the products prepared from the epoxide resin systems.
