acid salts may be used, with or without dilution of latex or with- 

 out heat prior to vulcanization. In Funtumia latex, or a pre- 

 served latex coagulable by heat, heat .done will suffice. Carbon 

 bisulphide, benzine, acetone or alcohol, or a mixture of the latter, 

 may be employed with or without heat. The addition to the 

 latex oi gas producing substances, such as carbonates or sul- 

 phides, modilies or increases the sponge formation if the coagu- 

 lation takes place in presence of an alkaline medium such as am- 

 monia. For vulcanization, sulphur, as such, or suitable sulphur 

 compound which will liberate sulphur may be used. The vul- 

 canizing agent is added eithei befon or during incipient coagu- 

 lation, and the mass may be directly vulcanized by subjecting it 

 to vulcanizing temperatures, either in open steam or hot air or 

 under water. The process permits the addition of fibrous sub- 

 stances, tillers, pigments, dyes or accelerating agents. The 

 patentees give ten different examples, showing the application of 

 their process. 



One of these, however, will be sufficient by way of illustration. 

 Equal quantities, by volume, of latex and of a saturated solu- 

 tion of ammonium carbonate mixed together are heated on a 

 water bath and one per cent., by weight, of finely divided sul- 

 phur stirred in. Coagulation may be induced by adding a suf- 

 ficiency of acetic acid while stirring the mixture. The containing 

 vessel is then placed in a steam vulcanizer and cured about one 

 hour at 286° P., the quantity of acid, curing time and tempera- 

 ture being varied according to the latex employed and the nature 

 of the sponge desired.
