Several poly(ethylene-co-methacrylic acid) copolymers have shown the unique ability to self-heal following projectile puncture, with the punctured site subsequently holding pressures in excess of 3 MPa. Four specific materials (ionomers and non-ionomer copolymers) were examined to determine if ionic interactions are responsible for puncture reversal. A range of novel experiments including peel, projectile, and quantitative post-puncture testing were used to determine that ionic content is not… 
Poly(ethylene-co-methacrylic acid) (EMAA) copolymers and ionomers have been observed to self-heal following ballistic puncture. Contrary to the repair mechanism of other engineered systems, the
Thermal characteristics of the self-healing response in poly(ethylene-co-methacrylic acid) copolymers
The results supported the defined healing model and provided additional information on the healing process in both its thermal dependence and general mechanism, and a new DSC method was developed for probing the thermal history of healed films which may lead to a more complete mechanistic model.
Effect of ionic content on ballistic self-healing in EMAA copolymers and ionomers
A specific class of poly(ethylene-co-methacrylic acid) copolymers and ionomers (EMAA) possesses a unique ability to instantly self-heal following ballistic projectile puncture. The present study has
Novel system with damage initiated autonomous healing property based on heterogeneous blends of ethylene-methacrylic acid ionomer
Abstract Self-healing behavior of ionomer blends containing both rapidly crystallizing phase and with higher amount of amorphous phase has not yet been studied. This work gives a new insight to
Mechanical properties of a thermally activated self-healing ionomer after ballistic penetration
Surlyn® 8940 ionomer is a copolymer of ethylene and methacrylic acid with thermally activated self-healing capacity. After ballistic impact was performed, mechanical, optical and thermal properties
Inducing hardening and healability in poly(ethylene-co-acrylic acid) via blending with complementary low molecular weight additives
The design and synthesis of low molecular weight additives based on self-assembling nitroarylurea units, and their compatibility with poly(ethylene-co-acrylic acid) copolymers are reported. The
Interlayer self-healing and toughening of carbon fibre/epoxy composites using copolymer films
Abstract This paper presents an investigation of the combined self-healing and toughening performance of two copolymers: thermoplastic poly(ethylene- co -methyl acrylate) (EMA) and poly(ethylene- co
Thermally Induced Healing of Electrically Insulating Ethylene–Octene Copolymers
We report on electrical insulating materials that not only have sufficient mechanical toughness to survive use conditions, but also possess the ability to undergo thermally induced self-repair when
Towards an understanding of thermally activated self-healing of an ionomer system during ballistic penetration
The self-healing phenomenon exhibited by the ionomer known as Surlyn 8940 (DuPont), a partially neutralized poly(ethylene-co-methacrylic acid) random co-polymer, during high-energy impact has been
Self-healing linear polymers based on RAFT polymerization
Self-healing polystyrene (PS) composites were fabricated, in which glycidyl methacrylate (GMA)-loaded microcapsules were embedded. Because the matrix PS was synthesized by reversible


Dynamic mechanical relaxations of ethylene ionomers
Metal salts (Li, MB, Na, and Zn) of poly(ethylene-co-methacrylic'acid) were studied using a dynamic viscoelastometer. The study reproduced the previous observation that the mechanical relaxation
Melt rheology of ethylene ionomers blended with a small-molecule acid
Abstract A novel EMAA ionomers with the incorporation of low molecular weight carboxylic acid have been developed to reduce melt rheology without changing the complete transparency of ionomers. Here,
Impact fracture behavior of ethylene ionomer and structural change after stretching
We carried out tensile impact test and very low speed tensile test on ethylene-based Ionomers (E/15wt %MAA) to clarify the relation between impact toughness and high-ordered structure. We also

Both tensile strength and toughness of sulfonated polystyrene (SPS) ionomers increased slightly at low ion content (below ca. 4 mol %) and increased significantly at higher ion content above 4 mol %,
Viscoelastic Behavior of Ionomers in Bulk and Solution
An overview is given of the viscoelastic behavior of ionomers in both the bulk and solution. For bulk materials, the various regions of the viscoelastic spectrum, i.e. glassy, glass transition,

Abstract : Clustering of ions in organic polymers is treated from a theoretical point of view. It is shown that ions in organic media of low dielectric constant exist most probably as pairs or higher
Ethylene Copolymer Ionomers
A discussion of the discovery of ethylene copolymer ionomers is presented. The structural features of ionomers and how these features are responsible for the physical properties of ionomers is given.
A new multiplet-cluster model for the morphology of random ionomers
The model is based on the existence of multiplets, which reduce the mobility of the polymer chains in their vicinity. Isolated multiplets act as large cross-links, thus increasing the glass
