| titleOfInvention | Perfluoropolyether-modified polysiloxane, a method for preparing the same and a defoaming agent comprising the same |
| abstract | The present invention relates to a perfluoropolyether-modified polysiloxane represented by general formula (1): nwherein X is a divalent group represented by formula -CH 2 -, -CH 2 O-, -CH 2 OCH 2 - or -Y-NR-CO-, nwherein Y is a divalent group represented by formula -CH 2 - or the following formula: nand R is a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an aryl group; nR 1 , R 2 , and R 3 are, independently of each other, an alkyl group having 1 to 10 carbon atoms or an aryl group; nX' is a divalent group represented by formula -CH 2 -, -OCH 2 -, n-CH 2 OCH 2 - or -CO-NR-Y'-, nwherein Y'is a divalent group represented by formula -CH 2 - or the following formula: nand R is as defined above; na is, independently of each other, 0 or 1; nz and z' are, independently of each other, an integer of 5 to 100; and nRf is a divalent group represented by the following general formula (2) : n-C t F 2t [OCF 2 CF(CF 3 )] m OCF 2 (CF 2 ) r CF 2 O[CF(CF 3 )CF 2 O] n C t F 2t -(2) nwherein m and n are an integer of 1 to 150, provided that an average of the total of m and n is 2 to 200; nr is an integer of 0 to 6; nt is 2 or 3; and nC t F 2t is linear or branched; nor by the following general formula (3): n-C t' F 2t' (OCF 2 CF 2 ) u (OCF 2 ) v OC t' F 2t' -(3) nwherein u is an integer of 1 to 200; nv is an integer of 1 to 50; nt' is an integer of 1 to 3; and nC t ,F 2t , is linear or branched. |
