ABSTRACT:
A polyhydridosilane has a catenated silicon backbone of 9 to 4000 silicon atoms with an average number of hydrogen atoms per silicon atom in the range of 0.3 to 2.2, at least 0.1 gram of the polyhydridosilane being soluble at 20.degree. C. in 100 grams of tetrahydrofuran, toluene, or methylene chloride. The polyhydridosilane can be derivatized or it can be converted to a pyropolymer or a nitrogen-containing pyropolymer which is useful as an abrasive, ceramic, electrical, or electro-optical material.
