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.
