Indeed, the OH groups at the end of the PHO-diol can (i) improve plasticization by creating interactions between the plasticizer and the matrix, but also (ii) limit a good dispersion in the matrix by locally creating weak bonds with other plasticizer molecules to form micro-aggregates. To this end, studies have shown that grafting long alkyl chains onto polar chain ends is a good strategy for adapting the ratio between the number of polar and apolar groups and obtaining good chain mobility.
