Abstract
The present invention relates to a new class of blowing inhibitors and a method for discovering such inhibitors with determinable inhibition activities. The new class of blowing inhibitors are organo-silanes that may be directly adsorbed onto active catalytic sites of blowing catalysts and that can inhibit the thermo-catalytic efficiency of such catalysts.
Claims8
A modifier for controlling decomposition of a blowing agent having a decomposition temperature comprising:
- a catalyst having an effective capability to reduce the blowing agent decomposition temperature;
- and
- an organo-silane adsorbed onto the catalyst, the organo-silane capable of inhibiting the effectiveness of the catalyst.
