Silicone Resins And Their Use in Polymers

摘要

The invention relates to silicone resins comprising metallosiloxane which contains Si—O-Metal bonds or borosiloxane containing Si—O—B bonds and potentially Si—O—Si and/or B—O—B bonds. It also relates to the preparation of such silicone resins and to their use in thermoplastic or thermosetting organic polymer or rubber or thermoplastic/rubber blends compositions to reduce the flammability or enhanced scratch and/or abrasion resistance of the organic polymer compositions. It further relates to coatings made of such silicone resins for scratch resistance enhancement or flame retardant properties.

主权项

1. A silicone resin comprising:
a. at least one metallosiloxane comprising Si—O-M bonds, wherein Metal M is chosen from Transition Group metals, IIIA Group elements, Zr and Sn; and b. at least one organic group comprising phosphorus and/or nitrogen with the proviso that when the Metal M is Al, the organic group is different than —(CH2)3NH2, c. wherein, when present, phosphorous is linked to Si through carbon atom(s).
