Abstract
A silacyclobutene compound having the formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently chloro, triorganosiloxy, organooxy, triorganosilyl, or a monovalent hydrocarbon group; R.sup.3 is a monovalent hydrocarbon group free of conjugated aliphatic unsaturation or triorganosilyl; R.sup.5 is hydrogen or a monovalent hydrocarbon group free of conjugated aliphatic unsaturation; and R.sup.4 and R.sup.6 are independently hydrogen or a monovalent hydrocarbon group free of conjugated aliphatic unsaturation or together are an alkanediyl group, wherein the alkanediyl group and the carbon atoms to which it is attached form a carbocyclic ring having 4 to 7 carbon atoms; provided that R.sup.3 is not aryl. Methods of preparing the silacyclobutene compounds, silane polymers containing at least one silacyclobutene unit, and siloxane polymers containing at least one silacyclobutene unit.
