DITERMINALLY SILANOL-MODIFIED PERFLUOROPOLYETHER COMPOUND AND PREPARATION THEREOF

Diterminally silanol-modified perfluoropolyether compounds of the general formula (1) This non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No. 2020-131626 filed in Japan on Aug. 3, 2020, the entire contents of which are hereby incorporated by reference.The present invention relates to a diterminally silanol-modified perfluoropolyether compound and to a method for preparing the same.Perfluoropolyether groups are building blocks containing a large number of fluorine atoms. Compounds having such a perfluoropolyether group (which compounds are referred to below as “perfluoropolyether compounds”), and coating films and articles obtained from compositions containing such compounds, have a very small surface free energy due to the effect of the many fluorine atoms included on the perfluoropolyether group, and thus exhibit, for example, water and oil repellency, lubricity, releasability and stain-blocking properties. Because of this quality, perfluoropolyether compounds are employed in a broad range of fields, including water and oil repellent finishes, lubricants, oil proofing agents, cosmetics and protective films.Perfluoropolyether compounds having functional groups at the ends of the main chain can be used to derive polymers having a perfluoropolyether skeleton by way of copolymerization with a reactive monomer or via reaction with a reactive resin. This makes it possible to impart, in addition to the properties of the polymer itself, the foregoing properties of perfluoropolyether groups. Perfluoropolyether compounds having functional groups such as (meth)acrylate, amine, alcohol, isocyanate, epoxy, thiol and vinyl groups and halogen atoms have been developed to date as such perfluoropolyether compounds.For example, JP-A 2005-200304 teaches the preparation of a perfluoropolyether compound having a functional group from a silane coupling agent by carrying out transesterification between, as the starting materials, a ...

The silicon nitride may range from amorphous to various crystalline forms and can include carbon doped materials or “silicon carbonitrides.” The most widely used manufacturing technologies for producing these films use the reaction of silicon precursors of silane (SiH) or dichlorosilane (HSiCl) with ammonia (NH) under thermal- or plasma-assisted low-pressure chemical vapor deposition (LPCVD), sub-atmospheric pressure CVD (SACVD), or atmospheric pressure CVD (APCVD). Unfortunately, plasma assistance necessitates temperatures in excess of 750° C. and thermal deposition processes require temperatures in excess of 1000° C. Plasma use also leads, in many cases, to the incorporation of excessive concentrations of hydrogen species, thus limiting the quality of the resulting SiN thin films.The use of these inorganic ...
