Research and Development /"x .VCk Monomer Analysis: CardinalChemical Stud^-'"'^
Dear John .
The two samples of VSKK Blend B-716 (one "treated" by Cardinal Chemicals) resins which you submitted have been analyzed by gas chromatographic analysis to determine their residual vinyl chloride monomer content. These samples were from the Ottawa, 111. plant. The "treated" sample supposedly was treated by Cardinal Chemical with an undefined material (possibly in a Henschel or in a Waring Blender to reduce the vinyl chloride monomer content).
Our analysis reveal that there has been a 64 percent
reduction in the vinyl chloride content; however, there still
remains some 77 ppm monomer in the treated sample. The control
sample contained 215 ppm vinyl chloride.

If I can be of further assistance please don't hesitate to call.

Vinyl Chloride Monomer Content in UCAR Latexes
The initial phase of our prop:ram to define existing status on the subject is completed. All production lots of Milt 31 (10) and UCAR 008 (7) have been chocked along with 10 lots of UCAR 1000 (7 from Somerset, 2 from Tucker, 1 from Alsip). The values obtained are in ppm by weight latex basis.
UCAR Latex 1000 Milt 31 UCAR Latex 508
Average 300 GOO GO
Std. Deviation 100 1G0 40
To place those numbers in perspective, please compare in ppm as shipped basis,

We obviously have a potential problem. The second phase of our program to define vinyl chloride release rates and equilibrium values in storage, handling1, and use is in progress.

Vinyl Chloride Monomer in DYNEL Resin
RECf/VeD
M O4 1974
k- N* wheeler, jr.
The 3 samples of DYNEL Resin which you submitted for monomer analysis have been successfully analyzed utilizing the recently developed technique used for PVC Resins. Basically the method is a gas chromatographic analysis using the flame ionization detector. The sample is dissolyed in THF solvent prior to injection into the chromatograph. Vinyl chloride monomer is calculated from the observed peak area which is applied to a calibration curv which has peak area plotted against concentration.
Our analysis show vinyl chloride monomer contents for Blend 5742 as bin No. 6, 180 ppm; bin No. 523, 90 ppm; and bin No. 523, 70 ppm.
It I can be of further assistance to you, please don't hesitate to call.
