Polymer nomenclature addition

The same publication [2] recommended a generic source-based nomenclature, which comprises the optional addition of a polymer class name to the source-based name of the polymer. The addition is recommended when it is necessary to avoid ambiguity or to add clarification. [Pg.263]

In addition to the Chemical Abstracts and lUPAC documents cited above and listed below, other articles on polymer nomenclature are available. A 1999 article lists significant documents on polymer nomenclature published during the last 50 years in books, encyclopedias, and journals by Chemical Abstracts,... [Pg.2191]

In addition to the Chemical Abstracts and lUPAC documents cited above and listed below, other articles on polymer nomenclature are available. A 1999 article lists significant documents on polymer nomenclature published during the last 50 years in books, encyclopedias, and journals by Chemical Abstracts, lUPAC, and individual authors. " A comprehensive review of source-based and structure-based nomenclature for all of the major classes of polymers," and a short tutorial on the correct identification, orientation, and naming of most commonly encountered constitutional repeating units were both published in 2000. ... [Pg.2185]

Recommendations on additional aspects of macromolecular nomenclature such as that of regular double-strand (ladder and spiro) and irregular single-strand organic polymers continue to be pubHshed in I ure and Applied Chemistty (100,101). Recommendations on naming nonlinear polymers and polymer assembHes (networks, blends, complexes, etc) are expected to be issued in the near future. [Pg.120]

The Commission on Macromolecular Nomenclature of the International Union of Pure and Applied Chemistry has published a nomenclature for single-strand organic polymers Pure and Applied Chemistry, 48, 375 (1976)). In addition the Association for Science Education in the UK has made recommendations based on a more general lUPAC terminology, and these have been widely used in British schools. Some examples of this nomenclature compared with normal usage are given in Table 2. [Pg.947]

The purpose of this monograph, the first to be dedicated exclusively to the analytics of additives in polymers, is to evaluate critically the extensive problemsolving experience in the polymer industry. Although this book is not intended to be a treatise on modem analytical tools in general or on polymer analysis en large, an outline of the principles and characteristics of relevant instrumental techniques (without hands-on details) was deemed necessary to clarify the current state-of-the-art of the analysis of additives in polymers and to accustom the reader to the unavoidable professional nomenclature. The book, which provides an in-depth overview of additive analysis by focusing on a wide array of applications in R D, production, quality control and technical service, reflects the recent explosive development of the field. Rather than being a compendium, cookery book or laboratory manual for qualitative and/or quantitative analysis of specific additives in a variety of commercial polymers, with no limits to impractical academic exoticism (analysis for its own sake), the book focuses on the fundamental characteristics of the arsenal of techniques utilised industrially in direct relation... [Pg.828]

In addition to structure-based and source-based names, there are traditional names (or retained names) for polymers which are widely used, particularly in industry but also in academia. When they meet the requirements of utility and when they fit into the general pattern of systematic nomenclature, these traditional names are retained. The following... [Pg.259]

Source-based nomenclature identifies the starting monomer(s) from which the doublestrand polymer is prepared with addition of an appropriate prefix "ladder- or "spiro- . Examples are ... [Pg.276]

It was first reported in the early 1970s that these melt processible polymers could best be described as thermotropic systems which usually display an nematic texture in the melt phase [5]. Subsequently, a number of additional phases have been reported ranging from discotic structures to highly ordered smectic E G systems with three dimensional order. In the last several years an IUPAC sponsored study on nomenclature on thermotropic LPCs has been underway. A more complete set of definitions will be available shortly as a result of Recommendation No. 199 IUPAC [6]. [Pg.223]

The evolving domain of radial, as well as linear, addition of modules to form an expanding moiety, in a manner akin to the development of polymers, referred to as "dendrimers", is examined and nomenclated The direct inclusion of topology in the description of isomers, once a very insignificant part of chemical nomenclature, is now a factor to be reckoned with, not only for the small class traditionally referred to as "topological" (including catenanes, rotaxanes, and knots), but also as new compositions of matter, such as the endothelial fullerenes, are formulated. [Pg.331]

The number of two-polymer and multipolymer combinations reported in the scientific and patent literature continues to rise without an adequate nomenclature to describe the several materials. More than 200 distinct topological methods of organization are already known (7,12) and new methods are being reported frequently. In addition to the usual molecular specifications, the time sequence of synthesis is important in many cases and needs to be preserved in the nomenclature for a full comprehension of the final product. [Pg.598]

Summary of Ring Notation. In summary, the addition of a zero, additive inverses, and coefficients allows for Laws One through Six to be followed. The polymer blend, graft, and IPN nomenclature scheme forms three rings, and the fact that the binary operation Om on R = (Pi, P2, P3,. . . , Pn) constitutes a group puts the system on an improved mathematical ground. Similar relationships can be developed for the other operations. [Pg.614]

A survey of the Additive Molar Functions (AMFs), which will be discussed in this book, is given in Scheme 3.3. There the names, symbols and definitions are given of the 21 AMFs from which the majority of the physical and physicochemical properties of polymers can be calculated or at least estimated. Scheme 3.3 is at the same time a condensed list of the Nomenclature used. [Pg.62]
