SILOXANE MODIFIED POLYOLEFIN COPOLYMERS |
摘要 |
<p>A siloxane modified copolymer with the following general formula: <IMAGE> wherein: x=1 to 1000; m=2 to 100; n=0 to 1000; z=0 to 2; y=1 to 3; (z+y)=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. A process for obtaining siloxane modified copolymer comprising: 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 DEG C. to about 350 DEG C. for not more than 1 hour at 50 to 350 rpm.</p> |
