Abstract
The present invention provides derivatives of native lignin having certain aliphatic hydroxyl content. Surprisingly, it has been found that consistent and predictable antioxidant activity may be provided by selecting for derivatives of native lignin having certain aliphatic hydroxyl content.
Claims9
A thermoplastic composition comprising a thermoplastic polymer and an annual fibre lignin derivative, wherein said lignin derivative has an aliphatic hydroxyl content of from about 1 mmol/g to about 3.75 mmol/g, a normalized RSI of 15 or greater and a polydispersity of from about 1 to about 5.
A polyolefin composition comprising an annual fibre lignin derivative, wherein said lignin derivative has an aliphatic hydroxyl content of from about 1 mmol/g to about 3.75 mmol/g, a normalized RSI of 15 or greater and a polydispersity of from about 1 to about 5.
