EMAGMA copolymer, containing 24% of methyl acrylate and 8% of GMA, Lotader[R] AX 8900, MFI = 6 g/10 min, density (ASTM D 792) = 0.94 g/[cm.sup.3], MP (DSC) = 65[degrees]C, modulus-E (ASTM D790) = 30 MPa, EB (ASTM D638) = 1100%, TS (ASTM D638) = 4 MPa, was provided by Arkema.
, studying the effect of EMAGMA copolymer on PET/EMA blend reported that the reactions between the carboxyl or hydroxyl groups of PET with the epoxy groups led to the increase in the molar mass.
The great difference of thin film morphology and thickness is contributed to the different self-assembly behavior due to difference of block copolymer
The same acetone vortex was set up to crash out the copolymer
. Vacuum filtration with grade 2 filter paper was used to isolate the copolymer
particles from the mixture.

, Polymer, 44, 7271 (2003).
For processors, the copolymer
grades are attractive because of the lower process temperature associated with lower crystallinity and also a wider process window.
The weight fraction of AMPS in the copolymer
was calculated according to the following equation :
Some block copolymer
films were introduced in a vacuum oven filled with nitrogen gas.
To prepare the PEO-b-PS thin film with different thickness, the PEO-b-PS diblock copolymer
powders were dissolved into purified chloroform (CH[Cl.sub.3]) in concentrations ranging from 0.01 to 0.5 wt%.
Theoretically, monodisperse gradient copolymer
latex particles can be synthesized by controlled/living polymerization technique that involves the simultaneous initiation of all growing chains with negligible chain transfer and easy cross-propagation.
As a processing aid, the metal-adhering properties of PHA copolymers
promote hogeneous shear melting of PVC and prevent overheating and degradation.
[ClickPress, Wed Jul 17 2019] Cyclic olefin copolymers
have gained significant popularity as preferred plastic in healthcare and packaging industries in recent years, in light of their compliance to various global regulations and norms.
