A process for the preparation of polyethylene terephthalate by making use of non antimony catalysts is described. The Ti complex catalyst is pre-dispersed in the polymer matrix selected from PET, PBT, PCTG, PETG, PCT, PEN, PPT, PTT or any other related polyesters and prepared as a master batch. The key feature of the process is that the polyester obtained is having good whiteness, as against the yellowness normally encountered with Ti based catalysts, and also the polyester has very good clarity with minimum haze.

There is provided a material which is free from fading into white due to surface scattering and is useful as a laminated article having excellent adhesion and practical low reflection. A fluorine-containing compound which has a hydrolyzable metal alkoxide moiety and is represented by the formula (1):wherein X1 and X2 are the same or different, and each is H or F; X3 is H, F, CH3 or CF3; X4 and X5 are the same or different, and each is H, F or CF3; Rf1 is a fluorine-containing alkyl group having 1 to 40 carbon atoms or a fluorine-containing alkyl group having 2 to 100 carbon atoms and ether bond, which is an organic group in which 1 to 3 hydrogen atoms are replaced by Y1 where Y1 is a functional group having, at its end, at least one hydrolyzable metal alkoxide moiety having 1 to 10 carbon atoms; a is 0 or an integer of 1 to 3; b and c are the same or different, and each is 0 or 1, a curable fluorine-containing polymer obtained from the above-mentioned compound, and a curable fluorine-containing resin composition comprising the polymer.

A skin care and shaving system is provided comprising disposable razor cartridge with one or more blades, skin engaging applicator member made of sponge like material and a handle for holding. The sponge like material includes small and large pore sponge and also foam pad which helps in applying all kinds of skin shaving enhancer such as shaving cream, lotion, gel, moisturizer during pre and post shave. Further, in another aspect of the present invention, it is provided a skin enhancer cartridge comprising a handle and a skin engaging applicator member without and razor blades attached to the system. The product of the present invention is a disposable one wherein the whole shaving system is disposable or in some cases the handle of the cartridge can be reused.

Ethylene-vinyl alcohol copolymer pellets comprise an ethylene-vinyl alcohol copolymer and water, and have a water content of not higher than 0.5 wt. %, wherein the ratio (Y / Z) of a lactone ring content (Y) to the sum (Z) of a carboxylic acid content (X) and the lactone ring content (Y) in terminal structures of the ethylene-vinyl alcohol copolymer is not less than 60 mol %. The pellets are excellent in high-temperature thermal decomposition-suppressing effect and thermal stability, and are free from odor emanation and coloration even if being processed at a higher temperature.
