Popis: | The co-oligomerisation of organic cyclosiloxanes with 1, 3-bis(3-glycydoxypropyl) tetramethyl disiloxanes in the presence of dimethylformamide, initiated by the tetramethylammonium silanolate and co-oligomerisation reaction kinetics was investigated. We found that the interaction of α, ω bis (3-glycydoxypropyl)methylvinylsiloxane with acetic acid proceeds through α-and β-junction reaction. The interaction of the same product with pyperazin gives only the products of β-junction. |
