摘要： Copolymers of at least three monomer units selected from the group consisting of fluorinated acrylic (methacrylic) monomers, triorganosilylacrylic (e.g. trimethylsilyl methacrylate) monomers and acrylic monomers not containing an organosilyl moiety, (e.g. methyl methacrylate) and optionally containing from 0-5 weight percent of a cross-linking agent are novel compositions useful as polymeric binders in long life marine antifoulant coatings. The erosion rate and resistance to cracking of the copolymer of the present invention when used as a binder in a marine antifoulant paint is controlled by adjusting the proportions of each monomer and the amount of crosslinking agent in the copolymer of the present invention

摘要： La presente invencion se basa en el descubrimiento de que los oxalatos de no titanilo pueden mejorar la funcionalidad catalitica de los catalizadores de oxalato de titanilo. Esta invencion proporciona una composicion catalitica novedosa que contiene un catalizador de oxalato de titanilo y un mejorador del catalizador de oxalato metalico y que contiene opcionalmente un cocatalizador metalico tal como un catalizador que contiene antimonio. Se ha descubierto una relacion sinergistica entre el catalizador de oxalato de titanilo y el mejorador del catalizador. Tambien se ha descubierto una relacion sinergistica entre el catalizador de oxalato de titanilo, el mejorador del catalizador y un cocatalizador metalico tal como el oxido de antimonio o el triacetato de antimonio. Tambien se proporciona un proceso mejorado para producir poliester mediante la policondensacion de reactivos formadores de poliester en la presencia de una cantidad cataliticamente efectiva de un catalizador de policondensacion, en donde la mejora comprende utilizar, como el catalizador de la policondensacion, la composicion catalizadora novedosa que contiene un oxalato de titanilo tal como oxalato de titanilo de litio y un mejorador del catalizador tal como un oxalato metalico de no titanilo, como el oxalato de litio y que contiene opcionalmente un catalizador metalico tal como oxido de antimonio o triacetato de antimonio. El proceso mejorado produce un poliester mejorado que tiene numeros de acetaldehido menores y un buen color. Esta composicion de oxalato de titanilo/mejorador del catalizador se puede usar como un catalizador de la policondensacion en combinacion con otros catalizadores, para conseguir la actividad catalitica sinergistica. Se prefiere una combinacion de oxalato de titanilo de litio o de potasio, Li2, o K2TiO(C2O4)2, oxalato de litio o de potasio, Li2, o K2(C2O4)2, con oxido de antimonio o triacetato de antimonio o trisglicoxido de antimonio.

摘要： A curable composition comprises an acrylic modified fluoropolymer and at least one crosslinking catalyst. The acrylic fluoropolymer is based on a vinylidene fluoride polymer selected from vinylidene fluoride homopolymer and vinylidene fluoride hexafluoropropylene copolymer wherein the acrylic portion of the polymer contains monomers residues having functional groups capable of entering into reactions whereby the acrylic portion becomes crosslinked provided that the functional groups do not include solely carboxylic acid groups and the vinylidene fluoride polymer comprises at least 70& wt of the total polymer.
