... polymer particles. One of the assumptions in the Smith and Ewart theory is that no new polymer particles are generated in the second stage of emulsion polymerization. The rate of polymerization per particle ... polymerization. Thus, polymer radicals lie only within these polymer particles. The total number of polymer particles per unit volume of emulsion in the second stag...

... molecular structure of the graft copolymer and the number of grafts formed. In addition, the length of the graft may vary, and the graft copolymer often carries a fair amount of homopolymer. The ‘‘graft-onto’’ ... classification of polymers is based on molecular structure. According to this system, the polymer could be one of the following: 1. Linear-chain polymer 2. Branched-c...
