Pyrolysis of Flat Sheet CMSMs

From the dry polymeric film so obtained, circular films of 1 diameter are punched out by a stainless steel die. When the die can not punch out the coupons, scissors are used to separate the eoupons from the film sheet. The coupons so produced are weighed and placed on a ribbed quartz plate as shown in Fig. 5.8. The quartz plate has 1/4 wide and 1/8 deep grooves which allow decomposition products to evolve from both sides of the film equally. 

The coupon is then plaeed in a pyrolysis fumaee, a quartz tube that is shown in Fig. 5.9.
