文摘
- •
A SEC-IR method for quantification of deuterium content as a function of MW is presented.
- •
The SEC-IR method is used on a series of LLDPEs subjected to catalytic hydrogen-deuterium exchange process.
- •
The H-D exchange process incorporates more deuterium in higher MW fractions than in lower MW fractions.
