Abstract: Disclosed is a shaped body exhibiting good long-term thermal stability, comprising at least one fluorohydrocarbon polymer which can be processed by melting, and at least one heat-resistant thermoplastic polymer, wherein at least the fluorohydrocarbon polymer forms a phase which is coherent or at least largely coherent. The weight ratio of the fluorohydrocarbon polymer to the thermoplastic polymer preferably varies between about 80:20 and about 20:80. The shaped body is preferably a film used as a layer of insulation.

Abstract: Disclosed is a multi-layer film having two or more layers, comprising at least one first layer of a polymer comprising a linear polyamide, and at least one second layer of a polymer comprising a linear polyamide containing from about 2 to 40 percent by weight of a hydrophilic substance compatible with the polyamide, such as polyvinyl alcohol.

Abstract: Disclosed is a multi-layer tubular packaging material having two or more layers, comprising at least one first layer of a polymer comprising a linear polyamide and at least one second layer of a polymer comprising a linear polyamide containing from about 2 to 40 percent by weight of a hydrophilic substance compatible with the polyamide, e.g., polyvinyl alcohol.

Abstract: This invention relates to a stretched shrinkable film of polyethylene terephthalate containing about 2 to 35 percent by weight of polybutylene terephthalate.

Abstract: Disclosed is a biaxially oriented polyester film, wherein the polyester comprises a linear polyester comprising a dicarbocyclic acid and a diol, and further including from about 3 to 20 mole percent of the dicarboxylic acid of a phosphorus-containing chain member having structural units of the formula ##STR1## wherein R is a saturated, open-chain or cyclic alkylene radical, an arylene radical or an aralkylene radical, andR.sub.1 is an alkyl group containing up to 6 carbon atoms, an aryl or an aralkyl group.Also disclosed is the use of this film as an electrical insulator.

Abstract: Disclosed is a composition, comprising a calcium-containing polyethylene terephthalate polymer and from about 0.01 to 1% by weight of silica obtained by a pyrogenic process, as well as a method of producing same and improved shaped articles made from said composition.

Abstract: This invention relates to a leader of an information carrier web suitable for photoelectric control, comprising a polyester film oriented by biaxial stretching, having one layer, and a transparency of at least 60 per cent when exposed to light of a wavelength of 750 nm.

Abstract: This invention relates to a stretched, shrinkable, tubular film of polyethylene terephthalate which has a lower initial point of shrinkage, higher shrinking values, and improved weldability, in which part of the ethylene glycol component is replaced by about 0.5 to 10 mole per cent of bis-phenol-A-bis-(2-hydroxyethyl)-ether.
