Jc. Russell et al., THE PREPARATION OF TRITIUM-LABELED BIOCOMPATIBLE POLYMERS, Journal of labelled compounds & radiopharmaceuticals, 33(10), 1993, pp. 957-964
The preparation of tritiated phosphoryl choline containing linear poly
mers by the reduction of an acetylenically unsaturated polymer with tr
itium gas is described. Homogeneous catalysis was used and the product
was analysed by H-1 and H-3-nmr spectroscopy. The use of lanthanide s
hift reagents showed that 98% of the isotope was located in the 7 and
8 positions of the hydrophobic chains.
