    • The invention relates to compositions comprising at least one polymer and at least one plasticizer, in which compositions the polymer is semi-crystalline and exhibits a processing temperature equal to or greater than 220null C., preferably 250null C., and the plasticizer is an aromatic benzenesulphonamide represented by the general formula (I) 1 in which R1 represents a hydrogen atom, a C1-C4 alkyl group or a C1-C4 alkoxy group, X represents a linear or branched C2-C10 alkylene group, or a cycloaliphatic group, or an aromatic group, Y represents one of the groups OH or 2 R2 representing a C1-C4 alkyl group or an aromatic group, these groups optionally themselves being substituted by an OH or C1-C4 alkyl group. The aromatic benzenesulphonamides have little volatility and exhibit good thermal stability, which makes it possible to effectively plasticize polyamides which are processed at high temperatures, such as polyamides-6, -6,6, -4,6, -6,9, -6,10, -6,12 and MDX-6 and polyketones, but also polyamides-11 and -12, polyoxymethylene and poly(vinylidene fluoride).
    • 本发明涉及包含至少一种聚合物和至少一种增塑剂的组合物,其中聚合物为半结晶的组合物,其处理温度等于或大于220℃,优选250℃,增塑剂为 由通式(I)表示的芳族苯磺酰胺,其中R 1表示氢原子,C 1 -C 4烷基或C 1 -C 4烷氧基,X表示直链或支链C 2 -C 10亚烷基或脂环族基, 或芳基,Y表示OH或R2中的一个代表C1-C4烷基或芳族基团,这些基团任选地本身被OH或C 1 -C 4烷基取代。 芳香族苯磺酰胺具有很小的挥发性并表现出良好的热稳定性,这使得有可能有​​效地增塑在高温下加工的聚酰胺,例如聚酰胺-6,6,6,-4,6,-6,9,-6 ,10,6-12和MDX-6和聚酮,还有聚酰胺-11和-12,聚甲醛和聚(偏二氟乙烯)。

    • The invention relates to pharmaceutical compositions which can be administrated orally, allowing the controlled release of at least one active substance comprising a) the said at least one active substance, b) between 5 and 60% by weight, relative to the total weight of the composition, of at least one excipient, selected from inert matrices, hydrophilic matrices, lipid matrices, mixtures of inert matrices and of lipid matrices, mixtures of hydrophilic matrices and of inert matrices, with the exception of mixtures comprising a polyacrylic acid and at least one hydrophilic matrix of the cellulose type; c) between 5 and 50% by weight, relative to the total weight of the composition, of at least one alkalinizing agent soluble in an aqueous phase under physiological pH conditions, selected from alkali or alkaline-earth metal hydroxidcs, carbonates, bicarbonates and phosphates, sodium borate as well as the basic salts of organic acids. It also relates to processes for the preparation of said compositions, multi-layered pharmaceutical compositions comprising at least one layer with this composition, as well as processes for the preparation of said multi-layered composition.
    • 本发明涉及可以口服给药的药物组合物,允许控制释放至少一种活性物质,所述活性物质包含a)所述至少一种活性物质,b)相对于所述至少一种活性物质的总重量为5至60重量% 至少一种赋形剂,选自惰性基质,亲水基质,脂质基质,惰性基质和脂质基质的混合物,亲水基质和惰性基质的混合物,除了包含聚丙烯酸和至少一种 纤维素类型的亲水基质; c)在生理pH条件下,选自碱金属或碱土金属氢氧化物,碳酸盐,碳酸氢盐和磷酸盐的至少一种可溶于水相的至少一种碱化剂,相对于组合物的总重量为5至50重量% ,硼酸钠以及有机酸的碱性盐。 它还涉及制备所述组合物的方法,包含至少一层具有该组合物的多层药物组合物,以及制备所述多层组合物的方法。
