Cyclic oligomers of poly(1,4-cyclohexylenedimethylene terephthalate) (PCT) were prepared by reaction of 1,4-cyclohexanedimethanol (CHDM) with terephthaloyl chloride under diluted conditions and separated from the linear products by silica gel column at a yield of 23.7 wt %. Cyclic dimer, trimer, tet
