Abstract
The present invention relates to a family of preferably bio-based plasticisers and resins containing said plasticisers. The disclosed plasticisers belong to the poly (ester ether) family. Resins containing the plasticisers exhibit a broad range of applicability in terms of suitable processing techniques and utilisation for final products.
Claims17
A plasticiser having a number average molecular weight of at least 1500 g/mol, the plasticiser comprising the following:
- a. dicarboxylic acids and dialcohols,
- b. one of a multifunctional alcohol or a carboxylic acid in a concentration below 20% by weight,
- c. a molecule with at least one ether moiety and reactive groups towards one of alcohols or carboxylic acids or a molecule capable of forming an ether upon reaction with the dialcohols, wherein the number average molecular weight of the molecule with at least one ether moiety and reactive groups towards one of alcohols or carboxylic acids is at least 140 g/mol and wherein the amount of cycloaliphatic molecules is below 50% by weight.
