EVALUATION 0? MONSANTO VGM VARIATIONS IN OPALON 440
Tex3 City Is providing four cars of Monsanto VCM,,each representing a variation in production operations* This memo
outlines the plan for evaluating these cars fn Opalon 440 polymerisation. 1/e would appreciate any comments on this plan from those receiving this memo,
OBJECTIVES
1, To cists mine the effect of VCM production variations on 440 latex stability,
2. To determine whether any of these variations is 1 satisfactory for further evaluation In 440.
EVALUATION CRITERIA
Acceptable VCM should give a coagulation frequency of 0 to 2 per 100 batches of 440, and a median of less than 375$ lumps per batch of 440. These criteria, have been satisfied in
IS65 while using Union Carbide VCM, and during February and May
of 1964 while using Monsanto VCM.
Evaluations in this experiment trill be based on an initial run of four 440 batches, followed, if not rejected, by running out the remainder of the car in 440,
These tests will lead to classifying each ear as acceptable for further evaluation, borderline unacceptable, or unacceptable, as follous;

will bo evaluated in late April - early Kay, as soon as 440 schedule
neraits.

3h?o methods of running the desired experiment are available Cue is to empty #1 tank, pump into this task the entire car to be
evaluated, transfer enough VGM for four batches, make the decision,
then transfer the rest either to paste or suspension area. The alternate is to pump twice directly from tko car to 84 VGM tank to make the first four batches, sake the decision, then transfer the rest either to #1 tank for paste {after emptying the tank) or to another tank for suspension.

Samples will be fcalsen in class bombs from each car, examined for appearance, and tested for &C1K If Springfield Control Lab has a suitable G-L?C tost at the time, 61?C analyses will also bo run on each ear, Additional samploo will he tahen and bold for possible Research evaluation. - details to bo developed with Research.
Senas City data will be available on each car.
