Title (EN) CONDENSATION POLYMER COMPOSITION FOR PREVENTING PREGNANCY
(FR) COMPOSITION DE POLYMERE DE CONDENSATION PERMETTANT D'EMPECHER LA GROSSESSE
Abstract:
(EN) This invention pertains to the discovery that condensation polymers of an aldehyde and aromatic sulfonic acids and fractions thereof, such as formaldehyde naphthalenesulfonic acid condensation polymers, can prevent pregnancy in an individual.
(FR) Cette invention tient au fait qu'on a découvert que des polymères de condensation d'un aldéhyde et d'acides sulfoniques aromatique, et de certaines de leurs fractions, et notamment les polymères de condensation de l'acide naphtalènesulfonique sous forme de formaldéhyde, permettent d'empêcher la survenue d'une grossesse chez un individu.
