How is the degree of emulsion polymerization related to the monomer concentration, and the rate of radical generation, Ri? , inversely proportional to Ri b) inversely proportional to Ri, directly proportional to . c) directly proportional to Ri, independent of . d) directly proportional to , independent of Ri

Correct Answer: and the rate of radical generation, Ri? ] directly proportional to , inversely proportional to Ri
The degree of polymerization is given by- Xn = Ʋp/Ʋi = kpN/Ri So, clearly the degree of emulsion polymerization is proportional to first power of and negative first power of Ri.

Monomer A is reacted with a monomer B in boiling methanol to form a salt. The salt dissolved in water with a little amount of acetic acid is then processed in autoclave at different temperatures and pressure. Monomer A is a bifunctional monomer having amine groups. What is the name of monomer B?

Let D be a simple graph on 10 vertices such that there is a vertex of degree 1, a vertex of degree 2, a vertex of degree 3, a vertex of degree 4, a vertex of degree 5, a vertex of degree 6, a vertex of degree 7, a vertex of degree 8 and a vertex of degree 9. What can be the degree of the last vertex?

How is the polymerization rate in emulsion polymerization dependent on the rate of radical generation?

A polymer ‘A’ is formed by the polymerization of monomer B. Monomer B is formed by the pyrolysis of monochlorodifluoromethane in contact with platinum at 700 ᵒC. Monomer is a highly crystalline polymer with excellent insulation properties. What is the name of monomer B?

Consider the following statements about emulsion SBR and solution SBR. I. Solution SBR has higher content of non-rubber materials than emulsion SBR II. Solution SBR has higher molecular weight but broader molecular weight distribution than emulsion SBR III. Solution SBR has higher cis-1,4-polybutadiene content than emulsion SBR Which of the following statements are true?

The styrene radical is apparently 500-1000 times less reactive than the vinyl acetate monomer, and also the styrene monomer is 50-100 times less reactive than the vinyl acetate monomer. State true or false.

How is the degree of polymerization affected with the increase in concentration of both monomer and liquid ammonia, when a monomer is polymerized anionically in liquid ammonia?

Emulsion polymerization is a type of polymerization that occurs in emulsion droplets called __________

Which order kinetics does the rate of polymer formation, in free radical polymerization, follow corresponding to monomer concentration?
