<p>THE PRESENT INVENTION RELATES TO PROCESSES FOR MAKING SYNTHETIC POLYISOPRENE LATEX AND SYNTHETIC POLYISOPRENE CONDOMS. A PROCESS FOR MAKING A COMPOUNDED SYNTHETIC POLYISOPRENE LATEX SUITABLE FOR MAKING A LATEX FILM COMPRISES (A) COMPOUNDING A SYNTHETIC POLYISOPRENE LATEX WITH SUITABLE COMPOUNDING INGREDIENTS, (B) MATURING THE LATEX AND OPTIONALLY (C) STORING THE LATEX; CHARACTERISED IN THAT STEPS (A), (B) AND (C) IF INCLUDED ARE CARRIED OUT AT A LAY TEMPERATURE SO AS TO MINIMISE PREVULCANISATION OF THE LATEX. CONDOMS CAN BE MADE FROM LATEXES PRODUCED ACCORDING TO THE PROCESS OF THE INVENTION.</p> |
