摘要：
The supermolecular structure of solutions of polyurethane and of polytetramethylene ether glycol is studied. It is found that spinning solutions having a large content of gel-particles are obtained from a more 'structurized' polytetramethylene ether glycol. Correlation analysis of the dependences of physico-mechanical fiber indices on parameters of the low-molecular compounds of spinning solutions showed that the specific load and load at 300% extension vary directly proportionally to the concentration and inversely proportionally to the size of particles in the spinning solution, and shrinkage in hot water varies in the opposite way.
