Preface
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 5576-1997 "Rubber and latex nomenclature". Compared with GB/T 5576-1997, except for the structural adjustment and
In addition to editorial changes, the main technical changes are as follows.
a) Added BIMSM, EBM, EOM, SEBM and SEPM to the “M” group (see 5.1);
b) GCO was added to the "O" group (see 5.2);
c) added HMQ, VEMQ and VEQ to the “Q” group (see 5.3);
d) The naming symbol of latex has been changed (see 5.4.1, 3.4.1 of the.1997 edition);
e) Added ANBR, BIR, DPNR, NBIR, NOR and HSBR to the “R” group (see 5.4.2).
This document is modified to adopt ISO 1629.2025 Rubber and latex nomenclature.
The technical differences between this document and ISO 1629.2025 and their reasons are as follows.
--- Added HMQ, VEMQ and VEQ (see 5.3) to adapt to the situation in my country;

Rubber and latex nomenclature
1 Scope
This document establishes a notation system for rubber and latex based on the chemical composition of the polymer chains.
This document applies to the nomenclature of rubber and latex.
NOTE 1 This document standardizes nomenclature used by industry, commerce, and regulatory bodies and is not intended to conflict with existing trade names and trademarks but rather to serve as a reference for their
Replenish.
Note 2.When the rubber name is used in technical documents or literature, the symbol is placed after the chemical name for later reference.
Note 3.For the nomenclature of thermoplastic elastomers, see GB/T 22027.
2 Normative references
This document has no normative references.
3 Terms and Definitions
There are no terms or definitions that require definition in this document.
4 rubber groups
Rubber and latex polymer chains are grouped and represented by symbols as follows.
M Rubber with polymethylene type saturated carbon chain
N Rubber containing carbon and nitrogen in the polymer chain
Note. There is no rubber represented by the N group symbol so far.
O Rubber containing carbon and oxygen in the polymer chain
Q Rubber containing silicon and oxygen in the polymer chain
R Rubbers with unsaturated carbon chains. Examples include natural rubber and synthetic rubbers made at least in part from conjugated dienes.
T Rubber containing carbon, oxygen, and sulfur in the polymer chain
U Rubber containing carbon, oxygen, and nitrogen in the polymer chain
Z Rubber containing phosphorus and nitrogen in the polymer chain
5 Symbol Groups
5.1 “M” Group
The "M" group includes rubbers having saturated chains of the polymethylene type, using the following symbols.
ACM is a copolymer of ethyl acrylate (or other acrylates) and a small amount of monomers that can promote vulcanization (commonly known as acrylic rubber)
AEM Copolymer of ethyl acrylate (or other acrylic acid esters) and ethylene
ANM Copolymer of ethyl acrylate (or other acrylates) and acrylonitrile
BIMSM Terpolymer of isobutylene, p-methylstyrene and p-bromomethylstyrene
