    摘要： A purpose of the present invention is to provide a siloxane suitable for preparing a medical material and a method for preparing the compound. The present invention provides a siloxane represented by the formula (1), wherein R1 is a hydrogen atom or a methyl group, R2 is a monovalent hydrocarbon group having 1 to 6 carbon atoms, L is a divalent hydrocarbon group which has 2 to 10 carbon atoms and may have one or more ether bonds, and A is a (poly)siloxane group represented by the formula (2) or (3), wherein n is an integer of 1 to 100, a is an integer of 0 to 10, b is an integer of 0 to 10, and c is an integer of 0 to 10, provided that a+b+c is 2 or more, and R is, independently of each other, a monovalent hydrocarbon group having 1 to 10 carbon atoms. The present invention further provides a method for preparing the siloxane, a polymer comprising recurring units derived from the siloxane, and a medical material, particularly an ophthalmic device, comprising the aforesaid polymer.

    摘要： Alkoxylated fatty acids are disclosed herein, as well as methods of making and using such compounds. In some embodiments, the alkoxylated fatty acids are formed from monomers derived from natural oils. In some embodiments, the alkoxylated fatty acids are used as surfactants for making synthetic latex by emulsion polymerization. In some other embodiments, the alkoxylated fatty acids are used as surfactants for making synthetic rubber, such as styrene-butadiene rubber. In some other embodiments, the alkoxylated fatty acids are used as surfactants in a composition for treatment of gas or oil wells, for cleaning applications, for use in various laundry-related applications, for use in personal care compositions, or for use as solvents for coating applications, such as reactive and non-reactive waterborne coating applications.
