Web2. nov 2024 · Refractive index increments have been determined very accurately for a linear, high density polyethylene, marlex 6050, in xylene for the wavelengths 436 and 546 nm. The observed values are compared with those calculated from aGladstone andDale expression and the agreement is found to be very good. WebRefractive Index: 1.465 (20 °C) Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water. PEG's are susceptible to oxidative degradation in the presence of air. Minimizing the exposure of PEG to elevated temperatures and/or exposure to oxygen, or addition of an antioxidant can limit the amount of degradation.
