Several membranes have been prepared by adopting the LbL technique for block copolymers that has proved to be an environment friendly approach in industries such as in gas separation, water purification and waste water treatment systems [16].
In our previous study block copolymers having general formula [(-CO-R'-CO-HN-Ar-NH- CO-R'-CO)xNH(CH2)3-(Me2SiO)y(CH2)3NH2]n [n=18.00 to 1175.0] where R'=CH2CH(CH2GeCl3);CH2CHGeCl3CH2;and Ar=-C6H4;-(o.CH3C6H4)2;-o.CH3OC6H4)2; (o.CH3C6H4) were synthesized by a polycondensation reaction of polyamide having a pendant trichlorogermyl group and terminal acid chloride Cl(-CO-R'-CONHAr-NH-CO-R'-CO-)xCl with aminopropyl-terminated polydimethylsiloxane H2N(CH2)3(Me2SiO)y-(CH2)3NH2] [21].
For processors, the copolymer grades are attractive because of the lower process temperature associated with lower crystallinity and also a wider process window.
Copolymers of AM and AMPS were synthesized via conventional free-radical polymerization.
Determination of Anionic Degree of Copolymers. The anionic degree of samples was determined by a back titration method [8] and by [sup.13]C-NMR spectroscopy.
For the molecular weight calculation of block copolymers, the average dn/dC was calculated from the dn/dC values for the corresponding homopolymers in the blocks and its molar composition (X) determined by NMR using the following equation:
As a processing aid, the metal-adhering properties of PHA copolymers promote hogeneous shear melting of PVC and prevent overheating and degradation.

[21] studied the effect of ethylene-butyl acrylate-glycidyl methacrylate (EBAGMA) and polyethylene octane elastomer grafted with maleic anhydride (POEgMA) copolymers on the properties of PET.
Inspired by the above researches, we designed and synthesized three tadpole-shaped POSS-based PMMA-b-PTFEMA weakly diblock copolymers using step ATRP technique.
Due to the presence of only one vinyl group in its structure, the VBT monomer is only able to form linear copolymers. However, since the bisVBT monomer has two vinyl groups, it has the potential to form branched and even cross-linked networks.
