“…Chemical modification of BR was carried out by oxidative chlorophosphorylation reaction with PCl3 in the presence of oxygen leading to the formation of PChBR (Step 1 in Scheme 1). The reaction procedure was described elsewhere in details [23][24][25][26][27][28]. It was emphasized that during the modification reaction of the polymer crosslinking process occurred between macromolecular chains.…”

“…Over the past few years, our group developed the synthesis of polymers with different types of phosphorus-containing functional groups by chemical modification (oxidative chlorophosphorylation reaction) of industrial polymerbutadiene rubber (BR) [23]. It was established that this reaction can be performed using readily available commercial reagents under mild conditions and in simple equipment.…”

“…The reaction scheme allows the synthesis of the respective products with the active P-Cl bonds that can be further modified for obtaining FSP with various functional groups. Thus, some phosphorus-(PCP) [23] and phosphorus/nitrogen-containing (PNCP) [24,25] polymers with different types of functional groups were synthesized by this method. The mentioned polymers were successfully applied for the formation of nanocomposites with magnetic nanoparticle [26], an adsorbent [27,28] and an extractant for preconcentration of metal ions by solid-phase extraction method [24][25][26].…”

In the present study the thermal behavior of phosphorus-and phosphorus/nitrogen-containing functional polymers was studied. The polymers were synthesized via oxidative chlorophosphorylation reaction of butadiene rubber and were subsequently subjected to hydrolysis, aminolysis and/or alcoholysis in order to introduce appropriate functionalities. The successful modifications of the polymer and presences of functional groups were determined using Fourier Transform Infrared Spectroscopy. It was found that the product of hydrolysis of the modified butadiene rubber contains acidic groups in its structure, the products of aminolysis and alcoholysis contain both acidic and amine and/or an alcohol derived moieties. The kinetic analyses of the thermal decomposition reaction were evaluated using thermogravimetric analysis and subsequently Friedman and Ozawa-Flynn-Wall methods. It was shown that degradation of the cross-linked polymers depends on the attached functional groups. The mass loss and the overall kinetic parameters of degradation showed complex mechanisms which characterize these thermal reactions.

“…and contain information relating mainly to the properties of the polymers obtained [7][8][9][10][11]. Our team for the first time have been investigated the oxidative chlorophosphorylation of diene polymers on example of butadiene rubber (BR) [12,13]. It was confirmed that during the oxidative chlorophosphorylation of BR by the action of PCl 3 in the presence of oxygen, functionally active groups with P-Cl bonds are introduced into the polymer matrix, as in the case of polyolefin polymers.…”

The reaction of oxidative chlorophosphorylation of styrene-butadiene rubber was studied by 1 H, 13 C, and 31 P NMR method. Investigations of functionalized styrene-butadiene rubber were carried out using low phosphorus containing samples selected from reaction medium at regular intervals. The obtained results have been discussed in detail, and make it possible to interpret the mechanism of the reaction and the structure of the polymer obtained.

Mineral‐rubber composites based on phosphorylated butadiene rubber (PhBR), including pure expanded perlite (EP) and modified phosphorylated expanded perlite (PhEP) as fillers, have been developed. The process involved forming PhBR and its composites – EP/PhBR and PhEP/PhBR‐through the oxidative chlorophosphorylation (OxCh) reaction. An in‐depth comparative analysis was conducted on the thermal destruction of the PhBR matrix and the EP/PhBR, and PhEP/PhBR composites. The thermogravimetric (TG)/differential thermogravimetry (DTG) analyses revealed three stages of thermal degradation for the PhBR matrix and both composites, highlighting the notable effects of EP and PhEP in the second and third stages of the degradation process. In comparison, the PhEP/PhBR composite exhibited reduced weight loss, the highest integral procedural decomposition temperature (IPDT) value, and a lower Tmax on the DTG curve, compared with the EP/PhBR composite and the PhBR matrix. The mechanism of the thermal destruction reaction and the kinetic parameters Ea and A were calculated using the model‐fitting Coats‐Redfern method.This article is protected by copyright.
