| 摘要 |
The present invention relates to a crosslinked network polymer obtained on the basis of an addition reaction of a hydrogen-containing polyorganosiloxane, an organic silicon resin and an unsaturated hydrocarbon, followed by the process of adding a crosslinking agent containing an active group and silicon dioxide; the polymer has an improved defoaming performance, good anti-foaming effect, and is easy to handle and process, and the addition of an emulsifier does not reduce the anti-foaming effect. The polymer has a good anti-foaming performance with no decay, and the polymer formed therefrom can easily be processed. |
