摘要 |
<p>The use of special organo-polysiloxanes as surface modifiers for finely divided particles such as pigments and fillers, or for glass fibres, is claimed. These cpds. are polysiloxanes of formula (I) contg. ester and/or epoxide gps. attached to Si via carbon atoms: R<1> = 1-18C alkyl, at least 90% of which are CH3 gps.; R<2> = 50-99% R<1>, 1-50% R<3> and R<4>; R<3> = a gp. of formula -(CH2)n-COOR<5> and/or -(CH2)3-O-CH2-CH(O)CH2 and/or -(CH2)2; R<5> = 1-4C alkyl; n = 3-20; R<4> = a gp. of formula -CH2-CH(CH3)-Ph; a = 1-500; b = 0-10; the ratio of gps. R<3>:R<4> = (1:25)-(10:1), but at least one gp. R<3> and at least one gp. R<4> must be present in the average mol.</p> |
