    摘要: The present invention relates to copolymers obtained by polymerizing a mono-functional silicone (meth)acrylamide monomer with a non-silicon containing, multi-functional (meth)acrylamide monomer having at least two (meth)acrylamide groups in a molecule. The shortest chain length of an organic group connecting any two (meth)acrylamide groups in the multi-functional (meth)acrylamide monomer is: i) 4 to 20 carbon atoms when every nitrogen atom of the (meth)acrylamide groups has at least one hydrogen atom directly bonded to the nitrogen atom; or ii) 1 to 20 carbon atoms when at least one nitrogen atom of any (meth)acrylamide groups has no hydrogen atom directly bonded to it.
