WebBulk polymerization is much more suited for step-growth polymers because these polymers have a (much) lower heat of polymerization and reactivity. Bulk … Bulk polymerization or mass polymerization is carried out by adding a soluble radical initiator to pure monomer in liquid state. The initiator should dissolve in the monomer. The reaction is initiated by heating or exposing to radiation. As the reaction proceeds the mixture becomes more viscous. The … See more Bulk polymerization has several advantages over other methods, these advantages are: • The system is simple and requires thermal insulation. • The polymer obtained is pure. See more There are two main types of bulk polymerization: Quiescent bulk polymerization There is no agitation in this type of bulk polymerization. This is often used to synthesize cross-linked and thermosetting polymers. Due to … See more
Synthesis of ABS resin with bulk polymerization process
WebIn solution polymerization, the neutral or ionic monomers are cross-linked with a multifunctional cross-linking agent in the presence of thermal, redox, or UV initiator.The major advantage of solution polymerization over bulk polymerization is the presence of the solvent serving as a heat sink. The prepared nano-hydrogel need to be washed with … WebApr 5, 2024 · Bulk Polymerization – It is also known as mass polymerization and is formed by adding a radical initiator to the pure monomer. However, the monomer must be in a liquid state, and the radical initiator should be soluble. The reaction is exothermic.
