For my project, I need to write a report about what is the state of the art for EVA foam, used in the bottom sole applications, recycling.
I am a bit confused and don't know where or how to search, which websites to check.
Can someone help me?

Controlled radical polymerization of ethylene was conducted through ITP. Copolymerization with vinyl acetate provides a range of well‐defined structures, including poly(ethylene‐co‐vinyl acetate) containing VAc from 0 to 85 mol %.
Abstract
Controlled radical polymerization of ethylene using different commercially available, cheap, and non‐toxic iodo alkyls is performed by iodine transfer polymerization (ITP) under mild conditions (≤100 °C and ≤200 bar). The formed well‐defined iodo end‐capped polyethylene (PE−I) species is very stable upon storage. Narrow molar‐mass distributions (dispersities around 1.6) were obtained up to number average molar masses of 7300 g mol−1. The ethylene copolymerization by ITP (ITcoP) with vinyl acetate allowed to form a broad range of poly(ethylene‐co‐vinyl acetate) (EVA) containing from 0 to 85 mol % of VAc unit. In addition, EVA‐b‐PE block copolymers or EVA‐b‐EVA gradient block copolymers with different content of VAc in the blocks were obtained for the first time using ITP. Finally, reactivity trends were explored by a theoretical mechanistic study. This highly versatile synthetic platform provides a straightforward access to a diverse range of well‐defined PE based polymer materials.

Different commercially available, cheap, and non‐toxic iodo alkyls (R‐I) were used as chain‐transfer agents (CTAs) in combination with 2,2’‐azobis(2‐methylpropionitrile) (AIBN) to investigate the impact of the R‐group on the polymerization behaviour. These systems showed no rate retardation and no significant loss of chain ends. The formed well‐defined end‐capped polyethylene–iodine (PE–I) species is very stable upon storage. Molar‐mass distributions with dispersities around 1.6 were obtained up to number average molar masses M n of 7300 g mol ‐1 . The copolymerization by ITP (ITcoP) of ethylene with vinyl acetate (VAc) to form poly(ethylene‐ co ‐vinyl acetate) (EVA) copolymer was also successful. By fine tuning the ethylene pressure and the vinyl acetate content, a broad range of copolymers containing from 0 to 85 mol% of VAc unit was achieved. By reactivating the iodo chain‐end, block copolymer structures composed of ethylene and VAc such as poly(ethylene‐ co ‐vinyl acetate)‐ b ‐polyethylene (EVA‐ b ‐PE) or gradient block copopolymers EVA‐ b ‐EVA with different content of VAc in the blocks were obtained for the first time using ITP. This highly versatile synthetic platform provides a straightforward access to a diverse range of well‐defined PE based polymer materials. Finally, reactivity trends were explored by a theoretical mechanistic study.
