POLYMERS WITH TRANSMISSION INTO THE ULTRAVIOLET

摘要

An ultra violet light transmitting polymer is obtainable by the polymerisation of at least one compound having a substantially non UV absorbing core group comprising; linear or branched aliphatic hydrocarbons which may contain an aliphatic ring; or polydialkylsiloxanes. The compounds have at least one functional group comprising formula (A), (B) or (C):and each of the groups -R³- are, independently, linking groups which may be present or absent and, where present, may be a C₁ to C₁₀ hydrocarbon chain, which may contain an ether linkage. Methods for producing the polymers and uses for the polymers are also described.
