Abstract
New procedure for obtaining natural resinous compounds modified in emulsion, characterized in effecting the emulsion, after dissolution of the natural resinous compound in a solvent medium appropriate to the nature of the resin in question in the proportion of 16:84 and separately dilution in water of an ether or mixture of cellulose ethers in the ratio of 9: 1, mixing the two solutions in an emulsifying apparatus at a temperature between 20 and 30 degrees c with strong agitation for a time ranging from 15 to 30 30 minutes until the stable emulsion is produced, for which the temperature and the speed of agitation are regulated to a limit such that the molecular electrical charges acquired by the resin enveloped by the colloid emulsifying agent are of the same sign.
