Bottlebrush Cell- g -PBA- b -PMMA Copolymer Elastomers with Disentangled Short Side Chains To Possess Applicable Mechanical Properties

The traditional thermoplastic elastomers are usually linear block polymers, and there is little research on bottlebrush copolymers as thermoplastic elastomers. The lengths of the grafted side chains are usually much shorter than those of the backbone of bottlebrush copolymers, so the mechanical properties are generally not strong enough for applications. Herein, we choose rigid cellulose as the backbone and the poly(n-butyl acrylate)-b-poly(methyl methacrylate) (PBA-b-PMMA) diblock as the side chains to obtain bottlebrush Cell-g-PBA-b-PMMA copolymer elastomers with disentangled short side chains, which still show applicable mechanical properties. It is found that the self-assembly of PBA-b-PMMA diblocks and…
