Nonhomopolymerizable monomers

The product may be of more complex structure if more than two monomers are utilized. For example, if nonhomopolymerizable monomers as described above402 are included at the beginning of the polymerization, the final product would have them on the periphery of the branched structure. Feeding the polymerization with different monomers would provide additional flexibility to this arms-first approach of making hyperbranched polymers. 

Hadjikyriacou et al. utilized the nonhomopolymerizable monomer DPE to prepare a variety of end-functionalized polymers. The reaction of DPE (1.25 molar equivalents) with the quasiliving TiCU-initiated IB polymerization is quantitative and only monoaddition occurs. Subsequent addition of l-methyoxy-2-methyl-l-propenyloxy-trimethyl silane or 1-cyclohexyenyloxy-trimethylsilane to the diarylcarbocation produced the ester- and ketone-fiinctionalized polymers. 

The results of more recent studies have revealed that copolymerization of the nonhomopolymerizable BL with CL and other monomers provides high molar mass polymers [59, 63, 64], For example ...
