          Application No. 08/365,384                                                  

          Claim 1.  A process for making substantially homogeneous                    
          polymers of at least two monomers having substantially                      
          differing reactivity rates, in a selected composition, by                   
          polymerization of said monomers, comprising:                                
               (a) precharging all of the slowest reacting monomer in an              
          amount in accordance with the selected composition, optionally              
          with part of one or more of said faster reacting monomers, and              
               (b) introducing the faster reacting monomer or monomers                
          independently and incrementally or continuously into the                    
          reactor at a specific feeding schedule for each monomer, as                 
          determined for each monomer before the polymerization by the                
          following equations:                                                        

          where A (t) has four adjustable parameters, a , a , a  and aj                                   1  2  3       4                
          for each monomer:                                                           
               a  determines the center of the distribution;                          
               a  affects the width of the distribution;                              
               a  determines the ascending portion of the distribution;
