Abstract:
A polymer mixture on the basis of a polyphenylene oxide which is suitable for wire insulation extrusion. The polymer mixture comprises a polyphenylene oxide, optionally a polystyrene, a hydrogenated block copolymer, an aromatic phosphate compound, a mineral oil and optionally usual additives. The invention also relates to an electrically conductive wire comprising an insulation built up from the above-mentioned polymer mixture and provided around the electrically conductive wire by wire insulation extrusion.
Abstract:
A thermally stable polyphenylene ether composition having long glass fibers of at least 4mm length therein. A suitable high temperature binder such as polyethyloxazoline may be included in the composition, as well as a flame retardant additive or other filler. The compositions are useful as engineering plastics.
Abstract:
High impact, high modulus thermoplastic molding compositions comprising: (a) a linear polyester; (b) a fibrous reinforcing agent essentially free of any sizing agent; and (c) a small amount of a polysiloxane having a substantial content of Si-H bonds.
Abstract:
Polyphenylene ethers are made more resistant to oxidation by adding an effective amount of oxalyldihydrazide. Optionally, a styrenic polymer may be added.
Abstract:
The sensitivity to stresses and the melt strength of thermoplastic polymer mixtures which comprise a polyphenylene ether and a polyvinyl aromatic compound can be improved by the addition of a polyfunctional dienophilic compound, for example, a bismaleimide or of a polyfunctional conjugated diene compound, for example, divinyl benzene.
Abstract:
High impact, high modulus thermoplastic molding compositions comprise (a) an aromatic carbonate polymer; (b) a linear polyester; (c) a fibrous reinforcing agent essentially free of any sizing agent; and (d) a small amount of a polysiloxane having a substantial content of Si-H bonds.
