ABSTRACT:
Novel .beta.-isocyanatoethoxy silanes and a method for their preparation is provided in which a 2-oxazolidinone is reacted with a halosilane to form a novel intermediate silyl-2-oxazolidinone product. The intermediate is then exposed to heat under reduced pressure to convert it to a .beta.-isocyanatoethoxy silane. The difunctional monomeric products are useful as starting materials for a variety of silicone and polyurethane prepolymers and polymers.
