AMINE-BASED REACTION PRODUCTS AS FUNCTIONAL ADDITIVES

The present invention relates to an adhesive composition comprising a condensate reaction product obtainable according to a process comprising: (i) reacting itaconic acid or an ester thereof with a diamine of formula H2N(CH2)nNH2, where n is an integer ranging from 2 to 12, wherein when n is an integer ranging from 3 to 12, the alkyl chain is a straight chain, in a molar ratio of diamine to itaconic acid or ester thereof ranging from 1:1.8 to 1:3.0 to form a first reaction mixture; (ii) heating the first reaction mixture to form a first condensate reaction product in a second reaction mixture; and (iii) optionally hydrolysing the second reaction mixture to form a second condensate reaction product, wherein the first condensate reaction product and the second condensate reaction product each independently has a weight average molecular weight (Mw) ranging from 200 to 499 g/mol.
