Modeling of batch production of high vinyl styrene/butadiene copolymers for high performance tires

Abstract

Mathematical modeling of batch production of high vinyl random styrene/butadiene copolymers in an industrial batch reactor was accomplished. Mass and energy balance equations were solved to model the nonisothermal anionic copolymerization of styrene/butadiene performed in an industrial batch reactor. The simulation model allows to predict the variation of the individual and global monomer conversion(s), temperature, pressure, and volume level of reactor with the time. Simulation model was used to determine the optimal polymerization conditions to maximize the production of a high vinyl random styrene/butadiene copolymer used in the manufacture of high performance tires.

Tires and Vehicle Lateral Dynamic Performance: A Corrective Algorithm for the Influence of Temperature

“…In fact, for each category (summer tires, winter tires) there is a different compound characterized by a typical range of p 1 (T g ) values. So, in accordance with [32][33][34][35], considering the fast evolution of research in the rubber field and considering the most common modern tire categories, the table shown below was built (Table 1).…”

“…Thus, being the state vector, {z}, equal to φ φ , and the input vector, {u(t)}, equal to a y , the roll dynamic matrix, [A] roll , is equal to: (35) the roll input gain matrix, [B] roll , is:…”

The transition mechanism of dynamic mechanical loss peaks and phase analysis in binary block copolymers of styrene/butadiene rubber

“…It is well-known that living anionic polymerization (LPA) enables precise control of the sequence structure, molecular weight, and distribution, along with other microstructural parameters of SBR. This allows for the synthesis of different polymer structures, such as random, block, and gradient copolymers, providing a powerful means to design rubber materials with diverse structures and superior properties [4][5][6][7][8][9] . Since the properties of polymeric materials are signi cantly in uenced by the microstructure of the polymers, the precise construction of polymer chain structures through directed synthesis has proven to be a potent strategy for controlling polymer properties [10,11] .…”

A Kinetic and Heat Balance Model for Anionic Batch Block Copolymerization of Styrene and Isoprene

“…This saves valuable time, costs, and resources. Model-based studies of anionic polymerizations exist for a number of different monomers and reactor types [13][14][15][16][17][18][19][20][21][22][23][24]. In all these studies, the focus was to describe the process of polymer synthesis as a function of all possible parameters that are influencing the product but all the safety and efficiency of the process.…”
