MRS Bulletin, 1987
Not much more than a decade ago, the plastics industry viewed itself as a mature branch of the heavy chemical industry. Its raison d'être was the mass production of four or five main-line polymers, and profits were equated to tonnage output, plant efficiency, and clever downstream processing such as film blowing.

Progress in Polymer Science, 1991
We will give first a broad classification of nematic, cholesteric and smectic phases. Then we will consider both lyotropic and thermotropic types of LCP's. The emphasis will be on providing a broad perspective of the remarkable properties of these materials rather than a detailed and rigorous treatment of selected ...

European Polymer Journal, 2000
Abstract A new series of poly(arylidene-ether)s containing cyclopentanone was synthesized by polycondensation of 4,4′-diformyl-α,ω-diphenoxyalkane 1 – 4 and 4,4′-diformyl-2,2′-dimethoxy-α,ω-diphenoxyalkane 5 – 8 with cyclopentanone. The inherent viscosity of the polymers were in the range of 0.38–1.23 dl/g.

Abstract Polysulfide liquid polymers are a comparatively recent development conceived at the Thiokol Laboratories in 1943. The development was initiated by the problem of finding methods to reduce the molecular weight of a polysulfide rubber which was too tough to process on conventional rubber milling equipment.

When the first edition of this book was published in 1975, it contained a chapter [1] entitled ‘Ultra-high modulus organic fibres’, which was based essentially upon literature published up to and including 1973. It dealt particularly with highly oriented aromatic polyamide fibres based on poly(p-benzamide), produced by spinning liquid crystalline ...

The idea of combining the anisotropic behaviour of liquid crystalline materials with the properties of macromolecular systems was first suggested by Onsanger and subsequently Flory. The actual realization that such systems could exist came from studies of natural polymers such as the tobacco mosaic virus.
