TLDR
In this paper, the authors evaluated a condition monitoring technique for aged polyethylene electrical insulation in nuclear power plants using dielectric spectroscopy and tensile testing, and the results suggest that the results can be used for in-situ measurements of the degree of oxidation of polyethyleni cables, in order to obtain information about the condition of the cable insulation to enable the remaining lifetime to be predicted.About:

Degradation Assessment of Polyethylene-Based Material Through Electrical and Chemical-Physical Analyses
TL;DR: In this paper, low-density polyethylene (LDPE) flat specimens were thermally aged under two different temperatures (90 °C and 110 °C) and analyzed through both the most common mechanical and chemical measurements techniques (e.g., tensile stress, thermal analyses, oxidation induction time).

Experimental investigation of the degradation mechanism of silicone rubber exposed to heat and gamma rays
TL;DR: The experimental results obtained in these analyses are clearly consistent with the mechanism that silicone rubber is degraded by forming cross-linked structures via formation of abundant siloxane bonds, and with further progress of degradation, decomposition becomes dominant.

Conference on Electrical Insulation and Dielectric Phenomena
TL;DR: The discovery and development of manmade polymer materials dates from the pioneering works of Goodyear (vulcanized rubber) and Hyatt (celluloid plastics) in the mid-nienteenth century, and to Baekeland (Phenol-formaldehyde resins) at the beginning of this century, the remarkable growth of the synthetic fiber, rubber, and plastics industries followed the preparative achievements of the I.C.I.
