M E M O R A N D U M TO: Executive Board of the Division of Polymer Chemistry (POLY) FROM: W. V. Metanomski SUBJECT: Nomenclature Committee's Report DATE: 7 September 1997 The Committee continues to promote polymer-nomenclature recommendations, in particular, those of the IUPAC Commission on Macromolecular Nomenclature. The most recent document that went through all stages of approval is on "Source- Based Nomenclature for Non-Linear Macromolecules". It is expected to be published in the December 1997 issue of PURE AND APPLIED CHEMISTRY. These recommendations are of particular interest to the POLY Committee, since Leslie H. Sperling, a member of the Committee, was the author of the very first draft. The Committee published in the September 1997 issue of POLYMER PREPRINTS "Macromolecular Nomenclature Note No. 13", explaining and promoting the new (December 1996) IUPAC "Glossary of Basic Terms in Polymer Science", especially the distinction between the "substance" (the "polymer") and the "macromolecule" of which the polymer is composed. The Committee provided a selected slate of terms with their definitions, derived from the IUPAC "Glossary of Basic Terms in Polymer Science", for publication in the new section "Definitions of Scientific Terms" of the CRC HANDBOOK OF CHEMISTRY AND PHYSICS. A dozen or so such terms were included in the 78th edition (1997-1998) of the HANDBOOK. Robert F. Fox, a member of the Committee, published an updated summary of the nomenclature rules for naming organic polymers in the CRC POLYMERIC MATERIALS ENCYCLOPEDIA published in 1996, and in the 77th edition (1996-1997) and the 78th edition (1997-1998) of the CRC HANDBOOK OF CHEMISTRY AND PHYSICS. W. Val Metanomski is preparing an updated introductory chapter on "Nomenclature" for the 4th edition of Wiley's POLYMER HANDBOOK. A new project has been submitted for consideration by the IUPAC Commission on Macromolecular Nomenclature, "Glossary of Polymer Class Names", with the supporting letters from several U.S. publishers of polymer textbooks and encyclopedias. Such an authoritative source is needed for authors and editors. The Committee members continue to represent the U.S. polymer science community on the IUPAC Commission on Macromolecular Nomenclature and participate actively in the generation and review of their new documents. Three Committee members (Fox, Metanomski, and Work) attended this year's meeting in Geneva, Switzerland, in August 1997. The Committee continues to be represented on the ACS Committee on Nomenclature. W. Val Metanomski is a member of the latter Committee. He presented a report on POLY Committee's activities at the ACS Committee's annual meeting on September 7, 1997, in Las Vegas. The Committee has a WWW page associated with the Divisional WWW pages: http://www.chem.umr.edu/~poly/nomenclature.html which lists the Committee members (links are provided to their full and e-mail addresses) and provides the list of "Valid Recommendations on Macromolecular Terminology and Nomenclature".
