It is manufactured using Ziegler-Natta catalysts based on transition metals.Depending on the metal used, the properties vary slightly. Using cobalt gives branched molecules, resulting in a low viscosity material that is ease of use, but its mechanical strength is relatively low. Nodymium gives the most linear structure (and therefore higher mechanical strength) and a higher percentage of 98% cis. Other less used catalysts include nickel and titanium. http://en.wikipedia.org/wiki/Polybutadiene Styron Buna® cis 132 este un cauciuc polibutadienic (BR) cu conţinut mare de unităţi cis, peste 95%, şi este produs cu ajutorul unui sistem catalizator pe bază de nichel. http://www.resinex.ro/produse/styronbr.html |
