ABSTRACT:
There is here provided a modifier for a resin containing an active hydrogen capable of reacting with an isocyanate group. The modifier of the present invention can give characteristics such as low frictional properties, water repellency, oil repellency and antithrombotic properties to the resin, and when the modifier of the present invention is used, neither bleeding phenomenon nor deterioration in mechanical strength takes place.
The present modifier comprises a modified polyorganosiloxane containing an isocyanate group which is represented by the general formula (A) ##STR1## wherein Me is a methyl group, Ph is a phenyl group, R is a methyl or phenyl group, R.sup.1 is H or a methyl group, each of m and n is 0 or more and a value of m+n is within the range of 0 to 600, a is 1, 2 or 3, b is 1, 2 or 3, c is a value of 1 to 300, and Q is a residue obtained by subtracting one isocyanate group from a compound having at least two isocyanate groups.
A process for preparing the compound having the general formula (A) comprises reacting a compound in which the moiety of --O--CO--NH--Q in the general formula (A) is not introduced yet thereinto, i.e., the moiety is --OH, with another compound having at least 2 isocyanate groups.
