摘要:
The invention relates to special (meth)acrylic monomers and concerns more particularly an enhanced process for preparing solutions of alkylimidazolidone (meth)acrylates in water from solutions of alkylimidazolidone (meth)acrylates in a light (meth)acrylate.
摘要:
Organic polymers having water contact angles of 20° or smaller, preferably 7° or smaller and equipped with both high wettability and high transparency. The organic polymers may contain as partial structures polar structures of about 3 debyes or higher in dipole moment and are available especially from polymerization of polymerizable compounds having alkylene(thio)urea structures.
摘要:
The invention disclose a hydrogen fluoride containing composition comprising hydrogen fluoride and a compound which is liquid in the standard state (25 °C, 1 atmosphere) and has a boiling point of 120 °C or more and pka of 12 or more at 25 °C, and use of the composition for a fluorination agent. The compound which can be preferably used is represented by the formula (1): wherein R 1 to R 4 are a substituted or unsubstituted alkyl or aryl group and can be the same or different, and R 1 or R 2 or R 3 and R 4 can bond to form a ring having a nitrogen atom or a nitrogen atom and other hetero atom, or R 1 and R 3 can bond to form a ring having a nitrogen atom or a nitrogen atom and other hetero atom. The fluorination agent of the invention exerts effect with a similar reaction mechanism to hydrogen fluoride, can be applied to the halogen exchange reaction of a halogen containing organic compound, and can produce a fluorine containing compound with safety and ease without specific equipment or technique.
