Abstract: The present invention relates to novel polymers ("polymer (P1)") obtainable by a process comprising the steps a) to c). According to step a), a polymer (P2) is provided. The polymer (P2) is obtainable by polymerization of a first dicarboxylic acid (A1) with a first diol (D1). Said polymer (P2) is hydrolyzed in step b) with a second diol (D2) in order to obtain a hydrolyzed polymer (P3). Afterwards, the hydrolyzed polymer (P3) is reacted with a second dicarboxylic acid (A2) which is different to the first dicarboxylic acid (A1), in order to obtain said polymer (P1). The present invention further relates to a process for obtaining such a polymer (P1). Furthermore, the present invention relates to the use of such a polymer (P1) within, for example, fabric and home care products. Another subject-matter of the present invention are fabric and home care products as such, containing such a polymer (P1).
