Method of melt blending curable polymer compositions using silicone hydrides |
摘要 |
Provided in one aspect is a method of melt blending comprising providing an extruder possessing addition points from a zero point to a 100 point the length of the extruder; adding at least one thermoplastic and at least one curable polymer at the zero to 10 point of the extruder; adding at least one silicone hydride at the 5 to 30 point of the extruder; adding at least one metal catalyst at the 20 to 60 point of the extruder, with the proviso that the metal catalyst is added at least 5 points farther down the extruder than the silicone hydride. Provided in another aspect is a hydrosilylation curative composition comprising a silicone hydride having the formula wherein H is hydrogen, and each R′ is independently selected from hydrogen and C1 to C10 alkyl groups; R″ is selected from C1 to C10 alkyl groups; n is an integer from 5 to 45; and m is an integer from 5 to 45.
