<p>A siloxane modified copolymer with general formula (I), wherein: x = 1 to 1,000; m = 2 to 100; n = 0 to 1,000; y = 1 to 3; and p = 1 to 200; wherein R and R1 are independently selected from the group consisting of hydrogen, alkyl groups having 1 to 6 carbons, phenyl, benzyl or alkylphenyl having from 6 to 12 carbons; R2 is selected from the group consisting of C1 to C6 alkyl, phenyl, benzyl or alkylphenyl having from 6 to 12 carbons; R3 is methyl, ethyl or propyl; and Z is O, S, NH or NR' wherein R' is phenyl, C1 to C4 alkyl or C1 to C3 alkylphenyl is prepared by the following process: reactively extruding organosiloxanes having reactive terminal groups with polyolefins having reactive groups, the molar ratio of the functional groups being from about 1:1 to about 1:100,000 in a substantially solvent-free environment at a temperature from about 150 °C to about 350 °C for not more than 1 hour at 50 to 350 rpm.</p> |
