    Abstract: Partially crosslinked siloxane-polyoxyalkylene block copolymer compositions having siloxane blocks linked to polyoxyalkylene blocks by silicon to oxygen to carbon (*SiOC*) linkages, the carbon of each said linkage being bonded only to the oxygen of said linkage, hydrogen and carbon. The siloxane blocks are comprised of siloxane units each having one to three monovalent hydrocarbon groups bonded to the silicon thereof and have an average of at least two valences of silicon per siloxane block combined in said linkages. A portion of the polyoxyalkylene blocks comprise oxyalkylene units and are crosslinking blocks having at least two valences of carbon per polyoxyalkylene block combined in said linkages joining separate siloxane blocks. The total of valences of silicon, combined in said linkages, of an average siloxane block plus the valences of carbon, combined in said linkages, of an average cross-linking polyoxyalkylene block is at least five. A portion of said polyoxyalkylene blocks are noncrosslinking or branching blocks having only one valence of carbon per block combined in said linkages, comprise oxyalkylene units and contain at least one of the groups of hydroxy, -OR, OOCNHR, and -OOCR groups in which R is monovalent hydrocarbon having 1 to 18 carbon atoms. The ratio of the number of polyoxyalkylene blocks to said siloxane blocks is 3:1 to 100:1 and the average number of silicon valences per average siloxane block combined with said polyoxyalkylene blocks times the weight percentage of said siloxane blocks in the composition is 20 to 150.
