Highly oriented low-modulus materials from liquid-crystalline polymers: the ultimate penalty for solubilizing alkyl side chains
A brief study of the effect of solubilizing, flexible alkyl side groups on the mechanical properties of highly oriented rigid-chain polymers is described. Experimental results obtained with poly(hexyl isocyanate) show that the side chains have a ruinous effect on the tensile modulus and stress at br...

Summary: | A brief study of the effect of solubilizing, flexible alkyl side groups on the mechanical properties of highly oriented rigid-chain polymers is described. 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 approx 90%. 28 ref.--AA |
