Controlling primary chain dispersity in network polymers: elucidating the effect of dispersity on degradation

Abstract

The development of a one-pot method to tune the primary chain dispersity in polymer networks and the notable effect of primary chain dispersity on gel degradation.

Network Polymer Properties Engineered Through Polymer Backbone Dispersity and Structure

“…[4][5][6][7][8][9] Recent advances in controlled and reversible deactivation polymerization methods have allowed unprecedented control over primary polymer structure. [10][11][12][13][14][15] In particular, reversible deactivation radical polymerization (RDRP) methods are among the most effective polymerization techniques for controlling the primary polymer structure. The desirability of RDRP methods arises from their ability to control the molecular weight of polymers with various functional groups, and to form complex polymers such as stars, block copolymers, and branched materials.…”

Chemical recycling of bromine-terminated polymers synthesized by ATRP

“…[1][2][3][4][5] In contrast, recycling efforts have lagged far behind, resulting in the accumulation of polymers within the environment and the necessity that new degradation and depolymerization methods are developed. [6][7][8][9][10][11][12][13] An alternative sustainable life cycle for polymers is idealized, where starting monomers can be directly reobtained from polymers, and then used to synthesize a new batch of materials. [14][15][16][17] However, developing these chemical recycling approaches is of considerable challenge, as the vast majority of polymers produced globally contain very strong all-carbon backbones and initial depolymerization strategies such as pyrolysis require very high temperatures (>400 °C) for monomer regeneration to be triggered.…”

“…Thus, high‐density polyethylene utilizes the higher rigidity imparted by crystallinity [4–9] . Recent advances in controlled and reversible deactivation polymerization methods have allowed unprecedented control over primary polymer structure [10—15] . In particular, reversible deactivation radical polymerization (RDRP) methods are among the most effective polymerization techniques for controlling the primary polymer structure.…”
