siloxane Chem.|sɪˈlɒkseɪn| [ad. G. siloxan (A. Stock 1917, in Ber. d. Deut. Chem. Ges. L. 170): see silicon, oxygen, and -ane.] Any compound having a molecular structure consisting of a chain of alternate silicon and oxygen atoms, the silicon atoms being bonded to hydrogen atoms or to organic radicals. Cf. silicone 2 a. Freq. attrib.
1917Jrnl. Chem. Soc. CXII. ii. 204 Perhaps the greatest confusion in the nomenclature of silicon compounds is to be found in the case of substances containing the {b1}Si{b1}O{b1}Si{b1} system. It is proposed to call the parent hydrogen compounds of this type ‘siloxanes’, and to specify the number of silicon and oxygen atoms in such terms as ‘disiloxane’, ‘disildioxane’, etc. 1941Jrnl. Amer. Chem. Soc. LXIII. 800/2 A cross-linked structure of siloxane chains. 1948Electronic Engin. XX. 82/3 The silicone oils are semi-inorganic polymers in which carbon atoms of organic radicals are linked to the silicon atoms of the so-called siloxane chain. 1960New Scientist 12 May 1205/2 Silicone rubber..is built up from purified siloxanes. 1974Encycl. Brit. Macropædia IV. 104/2 The most useful of man-made inorganic polymers are the siloxanes (also known as silicones). |
