New biobased prepolymers and their uses for the preparation of useful polymers as additives in a polylactide matrix
(EP2898000)
The present invention relates to the use of a compound having the following formula (I): (I) in which: – A1 is a divalent alkylene radical comprising from 2 to 20 carbon atoms; – A2 is a divalent alkylene radical comprising from 2 to 20 carbon atoms; – A3 is chosen from the group consisting of the following divalent radicals: an alkylene comprising from 2 to 600 carbon atoms; and an arylene comprising from 6 to 30 carbon atoms; – X1, X3 and X4 are ‐O‐ or ―NH‐; – X’2 is chosen from the group consisting of: ‐S‐, ‐CH2‐ and a bond; and – n and m are an integer of between 1 and 1000; for preparing additives in a polyester, polyvinyl chloride, polyurethane, polyamide, poly(alkyl acrylate), poly(alkyl methacrylate), polystyrene or polyolefin matrix.
