Ⅰ. Product name and structure
Product name: N-phenylmaleimide terpolymer
Abbreviation: NSM copolymer
Physical and chemical properties: The copolymer appears as white or light yellow powders. The
copolymer is insoluble in water, toluene and xylene, however, it can be soluble in organic solvents
such as tetrahydrofuran, dichloromethane, N, N-dimethylformamide, acetone, cyclohexanone, and
dimethyl sulfoxide.
Molecular structure: The molecular structure is a random amorphous copolymer, and the specific
molecular formula is shown in Fig. 1:

Ⅱ. Material Introduction
N-phenylmaleimide terpolymer is obtained by one-step solution polymerization of
N-phenylmaleimide monomer and other monomers. The copolymer has a high glass transition
temperature and excellent heat resistance stability, and has good compatibility with ABS and other
resins. It is a very effective and economical heat resistant modifier for ABS and other resins. It can
not only significantly improve the temperature resistance of ABS resin, but also improve its
processing performance and Hardness, which has effective modification effects for ABS resin.
Ⅲ. Basic technical indicators
IV．Application
As a heat resistant modifier for ABS, PVC, PMMA resins, and photosensitive materials, it can
improve the heat resistance, some mechanical properties (such as hardness, tensile strength, etc.),hot melt and processability of the resin. Adding 1% NPMI as a comonomer to ABS, the thermal
deformation temperature of ABS resin can increase by about 2 ℃. When 15% NPMI is blended
with ABS, the heat resistance temperature of ABS resin can reach 125-135 ℃. Our company's
products have superior heat resistance compared to similar Japanese products.
