摘要：
A de-foaming agent comprising by weight about(a) 80 to 100 parts of a polyoxyalkylene-polysiloxane copolymer of the formula:[R.sup.1 Si(OSiR.sub.2).sub.n ].sub.m Z.sub.m-1 (OR.sup.2).sub.m+2,in whichR represents an optionally halogen-substituted alkyl-group with up to 4 carbon atoms,R.sup.1 represents the substituent R or a phenyl radical,R.sup.2 represents a group of the composition ##STR1## Z represents the difunctional unit --O-- or ##STR2## and R.sup.3 denotes a hydrocarbon radical with up to 6 carbon atoms,R.sup.4 denotes independently from one another hydrogen or R.sup.3,n denotes a number between 3 and 40,m denotes a number between 1 and 15,x denotes a number between 0 and 68,y denotes a number between 0 and 52,x+y denotes a number between 1 and 68 andp denotes a number between 2 and 12,and (b) 0.5 to 20 parts of a hydrophobic silicon dioxide.
