  • Publication number: 20250129197
    Abstract: The present invention relates to novel graft polymers comprising a polymer backbone (A) as a graft base having polymeric sidechains (B) grafted thereon. The polymeric sidechains (B) are obtainable by polymerization of at least one vinyl ester monomer (B1) and optionally a further monomer (B2), wherein—if present—the weight ratio of monomer (B2) to monomer (B1) is less than 0.5. The polymer backbone (A) is obtainable by polymerization of ethylene oxide, and the molecular weight of the polymer backbone Mn in g/mol is within 500 to 5000. The present invention further relates to a process for obtaining such a graft polymer, the process is preferably carried out by free-radical polymerization. The present invention also relates to the use of such a graft polymer within, for example, fabric and home care products. Also claimed are fabric and home care products containing such graft polymer.

  • Patent number: 11149111
    Abstract: A process to prepare a (iv) cyclic polyester oligomer composition includes a cyclic polyester oligomer having furanic units and two to five repeat units. The process includes (a) reacting a monomer composition including: (i) a bifunctional furan-derivative and (ii) a diol in an linear oligomerization step to produce a (iii) linear oligomer composition including a linear oligomer species, (b) reacting the (iii) linear oligomer composition in a distillation-assisted cyclization (DA-C) step to form a (iv) cyclic polyester oligomer composition and a (v) diol byproduct. The (v) diol byproduct is removed by evaporation in the distillation-assisted cyclization (DA-C) step.
