Which of the following procedure is indicated to produce cross-linking in the polymerization of linear chains of acrylic_______________?
Correct answer: B. Addition of difunctional monomers
- A. Addition of grain refining agents
- B. Addition of difunctional monomers
- C. Increasing the amount of heat required for linear polymerization
- D. Incorporation of terminating agents
Explanation
Cross-linking requires monomers with two polymerizable functional groups, called difunctional or bifunctional monomers. They connect neighbouring linear chains into a three-dimensional network.
