| titleOfInvention | (meth)acrylated compounds based on recycled pet |
| abstract | The present invention relates to a process for preparing a polyester (meth)acrylate resin (I), said process comprising the steps of: n(a) Reacting a thermoplastic polyester with (a1) at least one polyhydric alcohol and, optionally, with (a2) at least one triglyceride, wherein the molar ratio of triglyceride to thermoplastic polyester is between 0 and 0.3, and the molar ratio of polyhydric alcohol to thermoplastic polyester is at most 1.9 to obtain a depolymerization product A that has a hydroxyl number within the range of from 200 to 800 mg KOH/g; n(b) Reacting the depolymerization product A with (b1) at least one fatty acid and/or (b2) at least one polybasic carboxylic acid and, optionally, with (b3) at least one polyhydric alcohol to provide a polyester polyol B; n(c) Reacting the polyester polyol B with (c) at least one (meth)acrylating compound to provide a (meth)acrylated compound (I), nwherein the weight ratio of fatty acid (b1) to the depolymerization product A is between 0 and 0.6, wherein the weight ratio of polybasic carboxylic acid (b2) to the depolymerization product A is less than 0.3, wherein the weight ratio of (meth)acrylating compounds (c) to the depolymerization product A is between 0.1 and 0.8,and wherein the (meth)acrylated compound (I) that is obtained has a number average molecular weight (Mn) of between 500 and 5,000 Dalton. Typically PET is used as starting material. Typically compounds (I) of the invention have a PET content of at least 15 wt%, preferably at least 25 wt%. n The present invention also relates to (meth)acrylated compounds (I) thus obtained and to coating compositions and inks based upon these materials. Materials of the invention allow the use of a high amount of PET waste. Inks and coatings prepared from these materials exhibit an excellent pigment wetting and/or ink-water balance. |
