Abstract
Abstract wherein R, R1, R16, R12, R13, R14 and R15 are selected from hydrogen and hydrocarbon radicals, while M is selected from sulfone and ketone groups, h is a whole number that varies from 2 to 20 and a is a whole number that varies from 0 to 2. This novel class of compounds are useful as flocculents for colloidal organic matter, as ingredients for detergent resistant polishes and as bonding agents for bonding various plastic resins and rubber to glass fibers and other types of glass material. A novel class of silicone compounds of the formula,
