摘要:
A magnetic disk comprises a substrate of a resin composition comprising a polymer being capable of the anisotropic phase in the molten state and a magnetic layer formed on at least one surface of said substrate. The substrate is a laminate of a plurality, preferably two, of monoaxially oriented sheets, eventually being multiaxially oriented.
摘要:
A laminated sheet comprises a first layer of a melt-phase anisotropy exhibiting thermoplastic polymer, having a negative linear expansion coefficient in the direction of the polymer flow and a second layer having a positive linear expansion coefficient in the direction of the polymer flow, both layers having been laminated one on another in the alternative way, further each layer having a thickness such that the negative linear expansion coefficient of said first layer and the positive linear expansion coefficient of the second layer having been offset against each other.

An electrically conductive resin composition comprises (1) a polymer of the thermotropic liquid crystals being capable of the anisotropic property in the molten state and (2) an electrically conductive carbon black. It is improved in the impact strength and can contain a large amount of carbon black.
摘要:
An electroconductive resin composite is produced by polymerizing at least one monomer a polymer of which is electroconductive in a matrix of a resin which exhibits the anisotropy in the melt phase to form a composite of the obtained polymer and the resin. The resin composite is obtained in the form of film and a moulded article.
