摘要

研究了自然老化和热氧化老化对受阻胺光稳定剂（HALS）稳定LDPE薄膜结构和物理化学性能的影响。基于多元线性回归分析（MLRA）建立了预测LDPE寿命的数学模型。使用四个统计标准来评估所开发的模型：残差方差、决定系数、Student检验和Fisher Snedecor检验。数学模型预测的半衰期具有统计学意义（p<0.05）。

The kinetic degradation of LDPE films subjected to aggressive environments

The effect of natural and thermo-oxidative aging on the structure and physicochemical properties of LDPE films stabilized with hindered amine light stabilizers (HALS) was investigated. Based on multiple linear regression analysis (MLRA) mathematical models to predict the lifetime of the LDPE were developed. Four statistical criteria were used to evaluate the developed models: residual variance, coefficient of determination, Student's test and the Fisher-Snedecor test. The half-life times predicted by the mathematical models were found to be statistically significant (p < 0.05).
