“…Polyakov, Dervitska, and Rogovin [84] showed that the thermal decomposition of cellulose methylxanthate gave rise to volatile products containing methyl mercaptan and carbonyl sulfide, and that the solid residue consisted of partly dehydrated cellulose, containing double bonds. In view of the difficulty of precise elucidation of the composition and structure of this product by chemical means, it was of interest to use spectroscopic methods for this purpose (204].…”

FOREWORDThis monograph is concerned with systematization of the infrared spectra of an important natural polymer, cellulose, and its derivatives.The infrared spectra of the main classes of cellulose derivatives are described and interpreted and those of such model compounds as mono-, di-, and trisaccharides are considered. Considerable attention is given to problems of technique in obtaining infrared spectra of fibrous cellulose materials, and to the analytical possibilities of infrared spectroscopy in studies of the properties of cellulose and its derivatives.The book will be of use to scientific and plant workers interested in the study and treatment of cellulose, compounds related to cellulose (carbohydrates and polycarbohydrates), and other polymers.

“…[1][2][3][4][5] By altering the chemistries used, amino acids or their derivatives can be attached to cellulose or other polymeric surfaces through reaction of either their amino or carboxyl functional group(s). Many applications that use surface-grafted amino acids exploit their abilities to selectively and efficiently recognize proteins and thereby resist or encourage surface adsorption of specific proteins.…”

Amide groups were anchored covalently on the surface of ethylene-co-acrylic acid (EAA) copolymer film by surface grafting of amino acid intermediates. The process consisted of four steps: conversion of carboxylic acid groups on the EAA surface to acid chloride groups, amino acid attachment, conversion of amino acid carboxyl groups to acid chloride groups, and amidation. All steps were carried out at room temperature. ATR-FTIR spectroscopy was used to characterize the film after each step and to measure the kinetics of amino acid attachment. Three amino acids were studied: 12-aminododecanoic acid (12-ADDA), 5-aminophthalic acid (5-APA), and l-aspartic acid (AA). The longerchain 12-ADDA compound was selected for its chemical similarity to migratory fatty amides that are commonly used to alter the frictional behavior of polyolefin films. The 5-APA and AA compounds were selected because each has two carboxylic acid groups that can be converted to amide groups. After amidation, the modified EAA films were characterized by static water contact angle measurements and scanning probe microscopy. Results showed that the 12-ADDA reacted to the surface much faster than the 5-APA or AA. Several steps of aggressive rinsing confirmed that the 12-aminododecanamide was chemically anchored onto the EAA surface. As a result, both hydrophilicity and surface roughness were increased.

“…The ester pyrolysis techniques have the advantage of positioning the olefin on the atom previously occupied by the alcohol, but they require temperatures of about 300°C. As Polyakov et al (1960) have shown, this leads to undesirable tar formations and side reactions when applied to polymeric alcohol compounds such as cellulose. The dehydrohalogenation procedures are somewhat more amenable to application on polymers, but require multistep procedures to produce the initial halogenated products.…”
