   <EMI ID = 1.1>

  
Divinylacetylene is known to react with chloride

  
hydrogen (hydrochloric acid) in the presence of solvents. or

  
diluents and catalysts forming dichloro (1,3)

  
 <EMI ID = 2.1>

  
Following this proceed divinylacetylene is stirred vigorously for a very long time with hydrochloric acid in

  
 <EMI ID = 3.1> <EMI ID = 4.1>

  
Not only does the addition, but also, in time, and more rapidly, polymerization. On this occasion, the

In these circumstances, we. could expect a reaction

safe and with excellent performance.

  
 <EMI ID = 7.1>

  
Individual constituents of this mixture can be obtained by simple rectification. The use of catalyst is almost
