The equipment provided in this grant is a special                               thermogravimetric system consisting of a Cahn Model C-1100                      Pressure Balance plus associated pressurization, temperature                    control, and data acquisition equipment.  Measurements will be                  possible at 700 degrees Celsius and 140 atmospheres, which                      represent conditions significantly beyond those capable with                    conventional thermogravimetric methods.  With this unique                       capability, characteristic diffusion and gas solubility  data                   will be possible for high temperature fluoropolymers and advanced               thermoplastics. Currently, such data are nonexistent and these                  properties can be estimated only through extrapolation of low                   pressure data which is expected to produce significant errors.                                                                                                  The ability to obtain such data, coupled with bubble nucleation                 and growth studies, should result in improved polymer foam                      processes and products with controlled open and closed cellular                 structures.  In the case of costly foamed fluoropolymer                         insulation for data transmission cable, small improvements in                   void fraction would result in significant material cost savings                 and superior products.  Also, studies of gas-polymer interactions               arising with SF6, Freon 123, and Freon 134 gases with various                   polymers should provide a basis for evaluating these gases as                   substitutes for the chlorine-containing freons which are                        currently used in polymer foam processes.  The latter gases have                been shown to have deleterious effects on the upper atmosphere                  ozone layer, and it is important that satisfactory substitutes be               identified.
