Synthesis and characterization of poly(vinyl chloride‐co‐vinyl acetate)‐graft‐poly[(meth)acrylates] by atom transfer radical polymerization

Abstract

ABSTRACT:The graft polymerization of methyl methacrylate and butyl acrylate onto poly(vinyl chloride-co-vinyl acetate) with atom transfer radical polymerization ( is the monomer concentration) versus time for the graft polymerization was almost linear, and the molecular weight of the graft copolymer increased with increasing conversion, this being typical for ATRP. The formation of the graft polymer was confirmed with gel permeation chromatography, 1 H-NMR, and Fourier transform infrared spectroscopy. The glass-transition temperature of the copolymer increased with the concentration of methyl methacrylate. The graft copolymer was hydrolyzed, and its swelling capacity was measured.

Synthesis of amphiphilic PVC-b-poly(hydroxypropyl acrylate) (PHPA)-b-PVC block copolymers with low PHPA contents and different molecular weights by (Single Electron Transfer)-(Degenerative Chain Transfer) living radical polymerization

“…show that the compositions of both fractions are similar. The presence, to very similar extents, of the carbonyl stretching band at 1727 cm −1 from PHPA units and the C‐Cl stretching mode at 616 cm −1 from the PVC units suggests that the coarse fraction is composed mainly of copolymer particles that may have agglomerated, possibly because of inefficient stirring in the reactor or owing to the use of an inefficient protective colloid system , as stated previously.…”

Synthesis, characterization and investigation of dielectric properties of two-armed graft copolymers prepared with methyl methacrylate and styrene onto PVC using atom transfer radical polymerization

“…Grafting of styrene and various acrylates was achieved by ATRP with the chloroacetyl group introducing to the polymer as initiating sites [14]. Percec and Asgarzadeh [15,16] and Bıcak and Özlem [17], and Chen and coworkers [18] reported the utility of ATRP in the grafting of some vinyl monomers by initiation via the labile chlorines of PVC.…”

Poly(vinyl chloride)‐b‐poly(hydroxypropyl acrylate)‐b‐Poly(vinyl chloride): Understanding the synthesis of an amphiphilic PVC block copolymer on a pilot scale

“…The PVC spectrum shows CCl stretching at 616 cm −1 . However, as shown in previous studies of PVC copolymers, the CCl stretching decreases greatly with the decrease of the PVC fraction in the copolymer . Hence, the low incorporation level of PVC in the block copolymer (around 10 wt.%, according to the elemental analysis) makes it extremely difficult to detect CCl stretching by using the FTIR technique.…”
