The invention relates to a mixture of a polyphenylene ether resin and a styrene-containing polymer or copolymer, in which at least a part of the polyphenylene ether resin is modified with reactive groups of a first type and at least a part of the styrene-containing polymer or copolymer is modified with reactive groups of a second type which are capable of reacting with the reactive groups of the first type. The invention further relates to articles formed from the said mixture, which have a good combination of low surface gloss and mechanical properties.

Polymer mixture which comprises a polyphenylene ether and a

The invention provides a low gloss polymer blend comprising an aromatic carbonate without reactive groups, a polymer or copolymer having a reactive epoxygroup and an aromatic carbonate polymer or copolymer having a reactive group which react with the epoxy group. Optionally, the composition may contain further usual compounds, such as polymeric materials which are normally used to modify the mechanical properties of polycarbonate, particularly rubbery or non-rubbery polymeric materials containing units of a styrene; also additives like colorants, flame retarding agents may be routinely incorporated.

Polymer blend with low gloss

Thermoplastic polyester, copolyester and polyblend molding compositions impact-modified by glycidyl methacrylate grafted EPDM exhibit high impact strength combined with good knit-line characteristics, when the grafted comonomer content exceeds 2 percent by weight in the impact modifier, it has a gel content in the range of from about 10 to about 80 weight percent.

Olefinic impact modifiers for, and blends with, thermoplastic polyester

The invention relates to polymer compositions comprising an aromatic polycarbonate, an aromatic polycarbonate with acid or ester functionality, a styrene based polymer and a styrene polymer with oxazoline groups. The polymer composition of the invention is suitable for molding objects with a mat surface.

Polycarbonate polystyrene composition

The invention relates to a polymer mixture which comprises an aromatic polycarbonate, a styrene-containing copolymer and/or a styrene-containing graft polymer and a flame-retardant. It has been found that the use of a certain type of flame-retardants, namely oligomeric phosphates leads to a polymer mixture having improved properties. In particular to a polymer mixture having a good combination of flame retardancy, non-juicing characteristics of the flame retardant, good plastifying effect and good heat resistance.

Polymer mixture having aromatic polycarbonate, styrene I containing

Thermoplastic compositions comprising polyphenylene ethers and polyesters, impact-modified by glycidyl (meth)acrylate grafted EPDM and compatibilized by an aromatic polycarbonate exhibit high impact strength alone and when combined with other impact modifiers. Their shear sensitive viscosity properties makes them uniquely suitable for extrusion and blow molding applications.

Composition

Blends of aromatic carbonate polymers with glycidyl methacrylate grafts on ethylene-propylene-diene modified elastomer (EPDM) further modified by reaction with an epoxy acrylate have low glass as well as improved impact strength and strong weldlines.

An antifoam composition is introduced as an aerosol into the main gas stream entering a gas-liquid separation tower. The main gas stream carries the small aerosol particles up the tower through the sieve-like separation trays and the water moving over the plurality of trays. The movement of the antifoam carried in the gas stream to the top of the tower is many times more rapid than the transit of liquid down the tower in countercurrent movement thereto. For antifoam particle sizes in the preferred range, movement of the antifoam continues unabated through a long series of trays in the tower to effectively inhibit foam formation therein.
