The present invention relates to administration forms having a relatively long gastric residence time, in the preparation of which mixtures of polymers containing lactam groups and polymers containing carboxyl groups are used, and which are distinguished both by marked swelling properties and by high dimensional stability in the swollen state.
摘要:
The invention relates to copolymers containing 0.01 to 35 mole-% relative to the total monomer composition, of one or more polymerized perfluoroalkyl group-containing monomer units, 55 to 99.99 mole-% of one or more polymerized N-vinylamide monomer units, and 0 to 10 mole-% of one or more further comonomers, a process for the preparation of the copolymers, and their use as emulsifiers and dispersants in aqueous systems.
摘要:
The present invention relates to electroviscous liquids consisting essentially of(I) a polymer or polymer mixture,(II) an electrolyte dissolved in (I),.(III) optionally an additive miscible with the solution of (I) and (II),(IV) optionally a viscosity-increasing additive reacting with (I);(V) a dispersant and(VI) a non-aqueous dispersion medium.
摘要:
The invention relates to new cleavable surface-active silane derivatives of the formula ##STR1## in which R.sub.1, n, R.sub.2, R.sub.3, X, m and R.sub.4 have the meaning given in the description, and furthermore processes for the preparation of these silane derivatives and the use of these compounds as surfactants.
摘要:
The present invention provides a solid shaped plant treatment product, a process for preparation of the product, and a method for use of the product in treating individual plants. The solid shaped plant treatment product contains a systemic herbicide which includes a herbicidally active compound homogeneously distributed in a polymeric carrier material. Suitable polymeric carrier materials bind the active compound in a solid form. The solid shaped plant treatment product can be implanted into a target plant in this form. Particularly, the solid shaped form is introduced into the vicinity of the vascular bundle system of the plant to be destroyed.
摘要:
The invention relates to a special process for the preparation of stable, solid medicament formulations of high bioavailability and with controlled release comprising sparingly soluble active compounds and polymeric auxiliaries, and to the formulations thus prepared.
摘要:
New pesticidal compositions which comprise at least one signal substance, at least one UV absorber which is only sparingly miscible with water, at least one unsaturated oil which is only sparingly miscible with water and, if desired, pesticidally active compounds and/or additives, a process for the preparation of the new compositions, and their use for controlling insects and undesirable representatives of the order Acarina.
摘要:
New pesticidal compositions which dry and harden after application, said compositions consisting of at least one pesticidally active compound, at least one signal substance, at least one liquid UV absorber which is only sparingly miscible with water, at least one curable polymer which, after drying of the formulation, has a sponge-like structure or forms a porous film at least one surfactant and, if appropriate, additives. The new compositions are very suitable for combating insects and undesirable representatives of the order Acarina.
摘要:
The present invention relates to a single or multi-layer recording material for recording images or data, which material has at least one layer sensitive to light or to heat of a plastic containing a pyrrole compound or a pyrrole oligomer.
