Applications of MQ-NMR to Elastomeric Silicone Materials

In a recent study [105], model end-linked PDMS networks were synthesized over a range of molecular weights both below and above the melt entanglement limit and subsequently studied by MQ-NMR. Using basic assumptions they were able to convert RDC distributions into effective molecular weight distributions via 

Polymer blends that contain multiple morphological domains have with them distinct segmental motions. Consequently Xe has been used to quantify ratios between crystalline and amorphous domains [119],
