Preparation of core–shell attapulgite particles by redox-initiated surface reversible addition–fragmentation chain transfer polymerization via a “graft from” approach

Abstract

Polymethyl methacrylate layer was grown uniformly from attapulgite by using surface-initiated reversible addition–fragmentation chain transfer polymerization via redox initiation system.

Recent Advances in RAFT Polymerization: Novel Initiation Mechanisms and Optoelectronic Applications

“…Generally, the effective redox initiator possesses a shorter induction period and higher monomer conversion. As Table 3 shows, persulfates and peroxides are two frequent oxidizing agents, which exhibit excellent redox initiation after coupling with a suitable reducing agent, such as benzoyl peroxide (BPO)/ N,N -dimethylaniline (DMA) [ 83 ], benzoyl peroxide (BPO)/aromatic tertiary amine functionalized ATP (ATP-ATA) [ 84 ], Potassium persulfate (KPS)/L-Ascorbic acid sodium salt (NaAs) [ 85 ]. An et al developed an aqueous redox-initiated RAFT polymerization system for fabrication of amphiphilic block copolymers [ 85 ] and highly ordered multiblock copolymer [ 86 ].…”

Compatibilization of polypropylene/poly(glycolic acid) blend with maleated poe/attapulgite hybrid compatibilizer: Evaluation of mechanical, thermal, rheological, and morphological characteristics

“…The surface functionalization of ATP has been confirmed the ideal approach to optimize its dispersity in the hydrophobic polymer matrix. Thus, the inorganic structure of fibrous ATP can create a nanoreinforcement effect, and the surface‐grafted organic component can promote the compatibility between the polymer blends . Compared with the short grafted chains, the long ones should be more effective to entangle with the polymer matrix and reduce the interfacial tension, especially the surface‐grafted chains with reactive functional groups .…”
