Abstract
An improvement in pre-ceramic methylpolysilanes that utilizes the reaction of methylpolysilanes with multiple-unsaturated compounds to reduce the number of ternary and highly reduced silicon atoms in the polymer matrix. Polymers thus modified are generally easier to process into ceramic fibers than prior art methylpolysilanes.
