Total Claims: 2
Claim 1
Independent Claim
83 words
IN A PROCESS FOR PREPARING BASIC LINEAR POLYMERS BY EMULSION POLYMERIZATION TECHNIQUES INCLUDING THE POLYMERIZATION OF A MONOMERIC SYSTEM COMPRISING A WEIGHED QUANTITY OF BASIC MONOMERIC MATERIAL SUBJECT TO POLYMERIZATION AND BETWEEN 0.01 TO 1.0 PERCENT BY WEIGHT BASED ON SAID BASIC MONOMERIC MATERIAL OF A POLMERIZATION INITIATOR, THE IMPROVEMENT WHICH COMPRISES: ADDING SAID MONOMERIC SYSTEM TO AN AGITATED AQUEOUS SYSTEM HAVING DISPERSED THEREIN BETWEEN 50 TO 100 MG. PER ML. OF A WATER-MISCIBLE ALKALI METAL SILICATE TO FORM THE EMULSION POLYMERIZATION SYSTEM.
