Graft Copolymerisation of Methyl Methacrylate onto a Bacterial Polyester Containing Unsaturated Side Chains

Poly(styrene peroxide) and Poly(methyl methacrylate peroxide) for Grafting on Unsaturated Bacterial Polyesters

“…P. oleovorans was grown on soybean oily acid substrate and the resulting polymer was extracted by using methods in the literature. [27] Substrates Soybean oil was extracted from the related agricultural products grown in Turkey. The acid obtained from the hydrolysis of soybean oil included both saturated and unsaturated acids in different weight percentages.…”

“…[26] Free-radical polymerization of MMA initiated by benzoyl peroxide in the presence of PHA-soybean also gives PHA-g-PMMA graft copolymers. [27] The first oligoperoxide was prepared by the reaction of phthaloyl dichloride with sodium peroxide. [28,29] Polymeric peroxides obtained by the polymerization of vinyl monomers with an oligoperoxide can be successfully used in the block copolymerization.…”

Synthetic routes to degradable copolymers deriving from the biosynthesized polyhydroxyalkanoates: A mini review

“…When exposed to air at room temperature for 40 days, the unsaturated copolyester formed a highly flexible and biocompatible elastomer [45]. The double bonds of the unsaturated PHAs can be homo-/copolymerized via free radical mechanisms to graft poly(methyl methacrylate) or by UV irradiating to graft PEG in the presence of benzoyl peroxide [46] and benzoyl peroxide [24], respectively. The halogenated PHU could be transformed to macro reversible addition-fragmentation chain transfer agents via the substitution reaction with potassium ethyl xanthate, which further initiated polymerization of N-isopropylacryl amide to obtain thermo-responsive and amphiphilic brush copolymers [47,48].…”

Graft copolymerization of glycerol 1,3-diglycerolate diacrylate onto poly(3-hydroxyoctanoate) to improve physical properties and biocompatibility

“…of MCL-PHAs with hydrophilic functional groups, such as carboxylic acid or amino and hydroxyl groups has not been successful [5]. Therefore, attempts to modify the properties of MCL-PHAs by chemical and physical methods, such as blending [6,7], crosslinking [8,9], and graft copolymerization [10,11], have attracted a great deal of interest.…”
