FACTORS AFFECTING ANTIBLOCK PERFORMANCE OF ETHYLENE VINYL ACETATE COPOLYMERS
Source abstract
Abstract
The antiblock performance of fatty amides was investigated in ethylene vinyl acetate (EVA) copolymers (VA = 28 wt% and MI = 400 g/10 minutes) and in low density polyethylene (LDPE). This investigation was done in an attempt to optimize the conditions for bulk shipments of these polymers in warm weather. Factors affecting the antiblock characteristics such as base resin, amide type, amide concentration, time and temperature were studied. Several analytical techniques were used including ATR-FTIR (both isothermal and non-isothermal in-situ measurements), HPLC, coefficient of friction (COF), stick temperature and dielectric constant measurement. The results indicate that the main mechanisms controlling amide antiblock performance are its ability to migrate to the polymer surface and its incompatibility with the polymer matrix.
