Research and Development $ub)ecf Vinyl Chloride Analysis PVC Resin and Films Dear Duane; The vinyl chloride monomer analyses have been completed on the latest PVC samples which we have received from you. Included in these samples were various resins, films, and two pieces of PVC tubing. For your convenience I have tabulated the results in Table I and as you can see they are essentially the same values obtained on all previously reported products. I am sorry for the delay in getting these results to you, but you are aware of the down time we experienced with the gas chromatograph. Looking forward to meeting you in person some day. nwm A.iE.
