IC = 11: POLYMERS INDUSTRY
PRODUCTION Table A1.1
FORMULATION Table A2.1
INDUSTRIAL USE Table A3.10 for polymerisation processes
In the polymers industry polymers are produced by:
A) Polymerisation reactions: A.1) “Wet” (e.g. emulsion polymerisation)
A.2) “Dry” (e.g. gas phase polymerisation)
B) Other (e.g. polyadditions, polycondensations)
The Use category (HEDSET) for all types of chemicals is: 43 Process regulators, which can be subdivided into:
Type Type of function
I Monomers (UC 43 Process regulators)
II Catalysts (UC 43 Process regulators)
III Initiators, Inhibitors, Retarders, Chain transfer agents (UC 43 Process regulators),
Vulcanising agents (UC 53 Vulcanising agents), etc.
N.B. 1. In principle this might be considered as stage 1. Production!
2. As no good information is available Process types “A” and “B” have been
considered to have the same emission factors
Compartment Conditions Emission factors
