摘要:
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.
摘要:
Modified phenolic resins and processes for producing these are described, as also are phenolic-resin formulations which comprise the modified phenolic resins, and processes for producing these. Specific uses of appropriate phenolic resins and, respectively, phenolic-resin formulations, and the use of block copolymers for producing phenolic resins, are also described.
