Organofunctional silanes and mixtures thereof Organofunctional silanes, including dimers and oligomers, are provided wherein individual silanes have both free and blocked mercaptan functionalities or particular mixtures of organofunctional silanes have both free and blocked mercaptan functionalities, organofunctional silanes and mixtures. of silanes are useful, among others, as coupling coupling agents for elastomeric compositions, for example, rubber formulations employed in tire manufacturing, where they exhibit a desirable balance balance of low wear and good performance properties. |
