Abstract
This application relates to certain novel hydroxyalkenylsiloxanes that are particularly useful as foam stabilizers for rigid polyurethane foams. The novel hydroxyalkenylsiloxanes have critical siloxane molecular weights and are produced by an addition reaction involving hydrosiloxanes and acetylenically unsaturated alcohols that contain a terminal acetylenic bond which does not shift significantly during the reaction.
