Silethynylenedisiloxane polymers are described with repeating units represented by -R1R2SiC(triple bond)CSiR3R4OSiR5R6O- where R1-R6 independently represent hydrogen atoms, alkyl groups, aryl groups, or alkenyl groups. The polymers are prepared by reacting a disilylacetylene compound represented by the formula X1R1R2SiC(triple bond)CSiR3R4X1 and a silane compound represented by the formula X22SiR5R6 where X1 and X2 represent H, OH, OM, or a hydrolyzable group. X1 and X2 are not identical and are selected so that they undergo a condensation reaction to form a siloxane bond.
