摘要: The invention relates to novel methylene bisphosphonic acid derivatives carrying a styrene group attached to the methylene carbon. The novel compounds are useful e.g. for functionalizing polymers of styrene type, especially macroporous styrene polymers, by copolymerizing the novel derivative with styrene and optional crosslinking agents. The invention also provides for new crosslinking agents especially suitable for the said purpose.

摘要: The invention relates to a process for the preparation of 3-substituted thiophenes in which the substituent is a C.sub.4 -C.sub.18 -alkyl group. According to the invention, the preparation is carried out by allowing an alkali metal salt of a C.sub.4 -C.sub.18 -alkyl-succinic acid to react with a compound of sulfur and phosphorus, e.g. tetraphosphorus decasulfide, in an organic solvent at a temperature of 100.degree.-180.degree. C., the product obtained being 3-(C.sub.4 -C.sub.18 -alkyl)thiophene. The said reaction may be the last step in a process in which the initial material is maleic acid anhydride with which .alpha.-C.sub.4 -C.sub.18 -alkene is combined so that C.sub.4 -C.sub.18 -alkenylsuccinic acid anhydride is obtained, whereafter this is hydrogenated catalytically to produce C.sub.4 -C.sub.18 -alkylsuccinic acid anhydride. This is thereafter reacted with an alkali metal hydroxide so that an alkali salt of the C.sub.4 -C.sub.18 -alkylsuccinic acid is obtained, which salt is reacted with a compound of sulfur and phosphorus to produce 3-(C.sub.4 -C.sub.18 -alkyl)thiophene, which constitutes the final product.
