Abstract
We have applied several H-1 solid state NMR techniques to obtain structural information on industrial silicone copolymers as thermoplastic elastomers that proved difficult to be analysed by conventional techniques. Static measurements were applied to achieve the separation between mobile and rigid parts. To get structural information fast magic angle spinning at 25 kHz in combination with a high field of 700 MHz was used. H-1 spin diffusion was applied to determine the domain sizes of the micro phase-separated polymer components. (C) 2002 Elsevier Science (USA).
