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