PURPOSE:An organopolysiloxane lubricant that contains an organopolysiloxane having a plurality of functional groups, thus being suitable for use in giving durable lubricity and releasability to synthetic resins and rubbers. CONSTITUTION:The objective lubricant contains, as the major component, an organopolysiloxane having 1 or more of 2 different kinds of functional groups selected from 4 different groups of -R<1>-COOH, -R<2>-SH and -R3-OY and -R<4>-X R<1>, R<2>, R<3>, R<4> are divalent organic group; Y is H, monovalent organic group; X is -CH2Cl, -(CF2)n-A (A is H, F; n is 1-8) , all of which bond to Si atoms in a molecule. The resultant lubricant is used usually by 0.05-20pts.wt. per 100pts.wt. of the synthetic resin or rubber. |
