The question of paper permanence is concerned primarily with the stability of cellulose fibers. Pure cellulose in its native state is a very stable material. Cellulose textile fibers have been preserved under favorable conditions for long periods without loss of integrity. It has been observed that many papers manufactured 100 to 200 years ago from cotton or linen fibers have retained their essential usefulness.

SPI continues to be used in paper manufacturing. Under selective conditions of pH and chemical reactants, the protein is modified to improve its influence as a coating modifier and dispersant (Coco et al., 1990). Only modified proteins are used in the industry today, and these modifications have continually improved the functionality of the protein (e.g., viscosity, water-retention, and pigment-stabilizing properties) and kept them competitive in the industry (Coco et al., 1990 Krinski Hou, 2000).

DUPONT offers eight sulfonate products for use in such diverse applications as textile and paper manufacture, metal working, petroleum, and agricultural chemicals. There are five alkyl sulfonates—PETROWET R ALKANOL 189-S and AVITONE A, P, and T—and three alkylaryl sulfonates—ALKANOL XC, WXN, and ND— all of which offer a combination of surface-active properties and good stability, making them valuable in a wide variety of industrial applications. PETROWET R and ALKANOL 189-S, XC, and WXN are surfactants ALKANOL ND and F are dyeing assistants and AVITONE P and T are softeners.

Lignin sulfonates are, technically, low-molecular-weight polymers containing a witch s brew of primary and secondary alcohols, phenols, and carboxylic acid functionalities. They are prepared by the sulfonation of lignin byproducts of pulp and paper manufacture, followed by neutralization to the sodium, calcium, or ammonium salt. The resulting materials are useful as dispersing agents for solids and oil/water emulsions, and as stabilizers for aqueous dispersions of dyes, pesticides, and cement. They are very inexpensive relative to other materials and are very... 

Stannic chloride is also used widely as a catalyst in Eriedel-Crafts acylation, alkylation and cycHzation reactions, esterifications, halogenations, and curing and other polymerization reactions. Minor uses are as a stabilizer for colors in soap (19), as a mordant in the dyeing of silks, in the manufacture of blueprint and other sensitized paper, and as an antistatic agent for synthetic fibers (see Dyes, application and evaluation Antistatic agents). 

In suspension processes the fate of the continuous liquid phase and the associated control of the stabilisation and destabilisation of the system are the most important considerations. Many polymers occur in latex form, i.e. as polymer particles of diameter of the order of 1 p.m suspended in a liquid, usually aqueous, medium. Such latices are widely used to produce latex foams, elastic thread, dipped latex rubber goods, emulsion paints and paper additives. In the manufacture and use of such products it is important that premature destabilisation of the latex does not occur but that such destabilisation occurs in a controlled and appropriate manner at the relevant stage in processing. Such control of stability is based on the general precepts of colloid science. As with products from solvent processes diffusion distances for the liquid phase must be kept short furthermore, care has to be taken that the drying rates are not such that a skin of very low permeability is formed whilst there remains undesirable liquid in the mass of the polymer. For most applications it is desirable that destabilisation leads to a coherent film (or spongy mass in the case of foams) of polymers. To achieve this the of the latex compound should not be above ambient temperature so that at such temperatures intermolecular diffusion of the polymer molecules can occur.
