A homogeneous composition having improved curability contains an organopolysiloxane having at least two carboxyl group-containing hydrocarbon groups in each molecule, a polymeric compound which contains at least 2 hydroxyl groups and at least one oxyalkylene unit and a catalytic quantity of an esterification reaction catalyst. The curable composition has good standing compatibility and experiences a high degree of curing. When cured the composition is useful, for example, as an antistatic additive.
Une composition homogène possédant une capacité de réticulation améliorée renferme un organopolysiloxane avec au moins deux groupes hydrocarbonés carboxylés dans chaque molécule, un composé polymérique contenant au moins 2 groupes hydroxyle et au moins une unité d'oxyalkylène et une quantité catalytique d'un catalyseur de réaction d'estérification. La composition réticulable offre une bonne stabilité de stockage et un degré élevé de réticulation. Une fois réticulée, la composition est utile, par exemple, comme additif antistatique.
