The following best illustrates a particular step in radical polymerization. Which step is it? R R R R R R نتثنتثر R R R R terminating the radical O forming the carbon radical propagating the carbon radical forming the radical initiator
DI Question 6 1 pts Consider the second step of initiation for radical polymerization where the active center is created. If "R" is the initiator fragment, what is the most likely configuration of the active center for the monomer shown below? O C O D D Question 7 1 pts
her concentration ovet lumer radicals, the 3. The overall rate of radical polymerization is measured as the decrease in monomer con time (AIM)/dt). If it is assumed that initiator radicals are equally as reactive as polymer radie reactions below can be produced showing the dissociation, propagation, and termination steps invalu in radical polymerization. a. Using the reactions provided, write the rate laws for each step. b Derive the equation for the overall rate of polymerization from the rate laws of...
Free Radical Polymerization Mechanism - Draw the mechanism for the polystyrene-forming reaction with the reactants shown below: a. Initiation b. Propagation c. Termination
Please write legibly thank you! 1. Give the detailed arrow-pushing mechanism for the free radical polymerization of methyl methacrylate. Show the initiation step and the addition of at least 2 monomers. You do not need to show a termination step, but do show the [ Jn notation of the final polymer. NEATNESS COUNTS heat poly(methyl methacrylate methyl methacrylate The initiator in this experiment, benzoyl peroxide, contains a weak 0-0 bond that undergoes homolytic cleavage at elevated temperatures. This leads to...
DRAW OUT STRUCTURAL REACTION FOR: 1. STEP POLYMERIZATION 2. RADICAL POLYMERIZATION 3. CATIONIC POLYMERIZATION 4. ANIONIC POLYMERIZATION 5. HOMOLYTIC AND HETEROLYTIC CLEAVAGE
In normal free radical processes with added initiator, the polymerization rate and kinetic chain length are proportional to the first power of monomer concentration. What would be the effect of monomer concentration on rate and chain length in the thermal polymerization of styrene (which involves no initiator)? Derive a kinetics expression to show this.Assume that initiation is based on the following equation: M + M -> 2 M. (radical in the product).
Which of the following statements is (are) true about free radical halogenation of alkanes? choose only one 1) The first of the chain-propagating steps is rate-determining. 2) The reaction proceeds by way of a flat sp2 hybridized free radical. 3) The chain-initiating step involves cleavage of a carbon-hydrogen bond to afford a carbon radical and a hydrogen atom. 4) Statements (The first of the chain-propagating steps is rate-determining) and (The reaction proceeds by way of a flat sp2 hybridized free...
Draw a mech. For polymerization using butylithium as initiator. Show the initiation one chain propagation step and use H+ to terminate growth.
