摘要:
The present invention relates to the field of polymerisation catalysts, and systems comprising these catalysts for polymerising carbon dioxide and an epoxide, a lactide and/or lactone, and/or an epoxide and an anhydride. The catalyst is of formula (I): wherein at least one of M1 or M2 is selected from Ni(II) and Ni(III)-X. A process for the reaction of carbon dioxide with an epoxide; an epoxide and an anhydride; and/or a lactide and/or a lactone in the presence of the catalyst is also described.

摘要:
In the liquid immersion lithography process, by simultaneously preventing deterioration of a resist film and deterioration of an immersion liquid employed during liquid immersion lithography which uses various immersion liquids, including water, resistance to post exposure delay of the resist film can be improved without increasing the number of processes, thereby making it possible to form a high resolution resist pattern using liquid immersion lithography. Furthermore, it is possible to apply a high refractive index liquid immersion medium, used in combination with the high refractive index liquid immersion medium, thus making it possible to further improve pattern accuracy. Using a composition comprising an acrylic resin component having characteristics which have substantially no compatibility with a liquid in which a resist film is immersed, particularly water, and are also soluble in alkaline, a protective film is formed on the surface of a resist film used.
