摘要：

This paper describes a brief study of the effect of solubilizing, flexible alkyl side groups on the mechanical properties of highly oriented rigid-chain polymers. Experimental results obtained with poly(hexyl isocyanate) show that the side chains have a ruinous effect on the tensile modulus and stress at break. Simple calculations reveal that the attachment of n-hexyl side chains reduces the theoretical axial modulus of rigid-chain polyamides by about 90%. © 1990, American Chemical Society.
