Title:
【発明の名称】ライオトロピック性の液晶質溶液
Document Type and Number:
Japanese Patent JP2924633
Kind Code:
B2
Abstract:
Novel compositions comprising a high concentration of one or more extended chain homopolymer, copolymer, or block polymer and certain polyphosphoric acids are prepared under conditions to exercise control of molecular weight as characterized by intrinsic visoscity. Such compositions are optically anisotropic (liquid crystlaline), capable of exhibiting excellent cohesive strength, and are especially suited to the production of high molecular weight ordered polymer fibers by dry-jet wet spinning. These liquid crystalline compositions are capable of being drawn through long air gap distances and spun at excptionally high spin draw ratios. Fibers, films and other articles formed from these liquid crystalline compositions exhibit exceptionally high physical and heat resistant properties.
