Low-frequency Raman spectra are reported for monodisperse methylene-oxyethylene-methylene triblock oligomers. Assignments are made to the longitudinal acoustical modes (LAMs) of the oxyethylene block and the methylene block. The results for LAM-1 can

Completely crystalline samples of oligoethylene glycol di-n-alkyl ethers, H(CH2)nO-(CH2CH2O)m(CH2)nH, where m is 9 or 15 and n is in the range 12-18, were orientated in capillaries by slow crystallization in a temperature gradient. X-ray scattering f

X-ray scattering from single crystals of the di-n-alkyl ethers of pentadecaethylene glycol with n = 13, 15 and 16 was consistent, for all practical purposes, with an orthorhombic unit cell including 4 molecules with space group Pcca. The long spacing

Block oligomers of the general formula CH3(CH2)nO[CH2CH2O]15(CH2)nCH3 where n + 1 = nc = 1 to 18 and 21 have been prepared. Both the oxyethylene and the methylene blocks are monodisperse. Examination of their crystallinity (by differential scanning c

X-ray scattering from continuously rotated samples of directionally crystallised pentadecaethylene glycol di-n-heneicosyl ether falls on a pattern of layer lines which is readily interpreted. The unit cell is orthogonal with a=0.938nm. b=9.13nm and c
