“…When the chloride group is removed by a Lewis acid (LA), a tertiary carbocation forms that can initiate polymerization. In recent years, a variety of polymers have been produced by copolymerizing IMs with other vinyl monomers, resulting in self‐condensing vinyl copolymerization (SCVCP). Materials produced by SCVP and SCVCP tend to be arborescent (tree‐like) in structure because the IM units lead to T‐shaped branch points.…”

A mathematical model is developed for the arborescent polyisobutylene system in a batch reactor, using multidimensional method of moments, to predict the concentrations of monomer and inimer as well as number and weight average molecular weight. This model is significantly efficient in computation, making parameter estimation practical. Simulation results agree with results obtained by Monte Carlo simulations. Parameter estimation results show that using the weight average molecular weight data provide better overall fit than leaving them out in the previous model.

“…Materials produced by SCVP and SCVCP tend to be arborescent (tree‐like) in structure because the IM units lead to T‐shaped branch points. These new polymers often have relatively low molecular weight . However, Puskas et al copolymerized IM and isobutylene to produce polymers with high molecular weight (>100 000 g mol −1 ) …”

Hyperbranched polymers (HPs) have widely been used for drug delivery owing to their highly branched topology, which endows the HPs with a large amount of intramolecular cavities for drug encapsulation and terminal groups for drug conjugation. Additionally, one-pot, large-scale preparations enable the easy fabrication of HPs for biomedical applications. This review provides an overview of the synthesis of HPs and their application for drug delivery. First, we introduce a diversity of methods for the synthesis of HPs with controllable topologies. Subsequently, we discuss drug encapsulation and drug conjugation by using HPs. Finally, we highlight the use of HPs with controllable topologies for promising drug delivery.

“…Organocatalytic polymerization provides new opportunities for metal‐free polymer materials . Phosphazene bases t ‐BuP 4 , one of the most powerful small molecule organocatalyst, can catalyze anionic or quasi‐anionic polymerization of various types of monomers including lactones, epoxy compounds, lactams, (meth)acrylates, fatty aldehydes and so on, affording polymers with predictable molecular weights and high end‐group fidelity under mild conditions . Interestingly, it was found that t ‐BuP 4 cannot catalyze the polymerization of styrenic and vinyl ether monomers .…”

Herein, we report one-step synthesis of polymethacrylates-based macromonomers (MMs) in the presence of an organocatalyst phosphazene base (t-BuP 4 ) and a functional initiator N-butyl-4-vinylbenzamide (N-BVBA) containing a secondary amide and a styrenic double bond. A series of styrenic MMs with controlled molecular weight and relatively narrow polydispersity were synthesized under mild conditions. Detailed NMR analyses of the initiation process suggested that the anionic polymerization was initiated by nitrogen anion generated from abstraction of the proton from the secondary amide. NMR and MALDI-TOF MS analyses confirmed: (1) the selective polymerization of methacrylate-type double bonds, (2) controlled chain-end functionality of MMs with an unreacted styrenic double bond, as well as (3) the absence of transesterification between N-BVBA and methacrylate monomers. Furthermore, the homopolymerization and copolymerization of the MMs with comonomers were carried out for the preparation of graft copolymers. Through conventional radical polymerization, graft copolymers with different grafting densities were obtained at high MMs conversions, indicating the high reactivity of MMs. Thus, the one-step approach demonstrates a simple metal-free access to the controlled synthesis of MMs, and the prepared MMs can polymerize efficiently to convert into graft copolymers.
