摘要:
The opening in a flexible container for wine and fruitjuice of a rubber-lined or coated synthetic fabric is closed by a gas- and liquidtight zipper. An easy and unproblematic cleaning of the container is possible due to the easy opening and closing of the zipper.
摘要:
A filter device suitable for filtering sludges which comprises (A) a tube-like filter as an outer wall consisting of a fabric of polyester or polyamide filament yarn which acts as a support for (B) an inner layer consisting of a non-woven fabric of man-made fibres and a process of dewatering industrial sludge.
摘要:
Polycarbonate molding compositions resistant to light aging and exhibiting an improved notched impact strength are disclosed. The compositions which are based on an aromatic polycarbonate, aromatic polyester carbonate or a polyester, contain a redox-catalyzed graft polymer of resin-forming monomers on a rubber, a phosphorus compound and a fluorinated polyolefin.
摘要:
Thermoplastic molding compositions containingA) ABS-type resin,B) aromatic polycarbonate resins,C) a compound bearing several carboxyl groups or mixtures thereof and optionallyD) further polymer resins,characterized in that an ABS resin with at least one basically acting additive is used as component A, component C is selected from compounds having a molecular weight of from 150 to 260 having at least two carboxyl groups (--COOH) in the molecule, and the weight ratio of basically acting additive in A: carboxyl groups in C is from 5:1 to 1:1.
摘要:
Particulate graft polymers composed of a core (a) of cross-linked diene rubber, a first envelope (b) of a cross-linked acrylate rubber, a second envelope (c) of a copolymer of resin-forming monomers and polyallyl monomers having at least three allyl groups in the molecule, and a third envelope (d) of a copolymer or homopolymer of resin forming monomers.
摘要:
A thermoplastic molding composition is disclosed comprising(i) a thermoplastic resin(ii) a low molecular weight additive, and(iii) a specially prepared carrier material magnesium-aluminum-silicate.The carrier material which is characterized by its particle size and low bulk density was found to be effective in minimizing the thermal processing-related evaporation of the low molecular additive.
摘要:
Thermoplastic moulding compounds based on fully aromatic polyester carbonates polyalkylene terephthalates and grafted diene rubber have a well balanced combination of notched impact strength at room temperature and low temperatures and high weld line strength and may be used for the production of moulded articles, in particular by injection moulding.

摘要:
Copolymers of blocks of polymers of cyclic aliphatic carbonates, cyclic aliphatic esters or cyclic aliphatic carbonates and cyclic aliphatic esters on the one hand and blocks of polymers of cyclic aromatic carbonates on the other hand and a process for their production by multistage polymerization, in which a block polymer is initially prepared from the aliphatic monomer and the aromatic polymer is produced in the presence of this block.
