          Interference No. 103,029                                                    

                    The subject matter of the interference deals with                 
          the terpolymer of acrylonitrile, butadiene, and styrene                     
          called ABS.  KR340.   In making structural shapes of ABS, such4                                                        
          as toolboxes or tote bins, it is desirable to improve the                   

          properties of the polymer so that it readily dissipates static              
          electricity.  The antistatic properties are improved by                     
          blending the ABS with a copolymer elastomer formed of                       
          epichlorohydrin   and ethylene oxide.  This copolymer is                    
          referred to by the abbreviation ECH/EO.  KR342.  The ethylene               
          oxide is the effective antistatic ingredient.  KR342.  The                  
          amount of electrostatic dissipation (ESD) is measured with                  
          respect to a military specification that requires a charge of               
          5000 volts to be dissipated in 2 seconds  or less.  KR343.5                                   

               4    The Kipouras record and Kipouras exhibits will be                 
          abbreviated KR and KX-, respectively, followed by the                       
          appropriate number.  Likewise, the Barnhouse record and                     
          exhibits will be abbreviated BR and BX-.                                    
               5    Giles also testified as to ABS-ECH/EO blends that                 
          would dissipate a 5000 volt charge in one second.  KR343;
