correspondto the geometry at platinum (see text) and can
be separated by recryatdlization. The isomer ratio was determined by
'H NMR spectroscopy. *Monomer contains 30% 4-
ferential scanningcalorimetry. However,the polymers 3
and 5 exhibit a broad endothermic transition over the
rangeW160 "C, with the peak at 115"C,and the melting
endotherm begins at 210 "C and peaks at 245 "C. When
samplesof polymers3and 5 were heated to 150"C for 30
minand then cooled and reheated, the broad endotherm
in the region 60-160 "C was not obrved. Thus,it appears
