Polyester polyols from thermoplastic polyesters and dimer fatty acids

Polyester polyols made from thermoplastic polyesters are disclosed. The polyols can be made by heating a thermoplastic polyester such as virgin PET, recycled PET, or mixtures thereof, with a glycol to give a digested intermediate, which is then condensed with a dimer fatty acid to give the polyol. The invention includes a polyester polyol comprising recurring units of a glycol-digested thermoplastic polyester and a dimer fatty acid. The polyester polyol can also be made in a single step by reacting the thermoplastic polyester, glycol, and dimer acid under conditions effective to produce the polyol. High-recycle-content polyols having desirable properties and attributes for formulating polyurethane products, including aqueous polyurethane dispersions, can be made. The polyols provide a sustainable alternative to bio- or petrochemical-based polyols.

Unsaturated polyester composition for autobody repair with improved adhesion to metal substrates

A vehicle body repair formulation is provided that includes a polyester resin having a degree of unsaturation of between 25 and 100 molecule percent based on total acid and anhydride content. The polyester resin is dissolved or suspended in a monomer reactive diluent. Microspheroids are provided to enhance the sandability of a cured formulation. An initiator package is also provided. The reactive diluent/monomer can be chosen to be non-stryrenic to improve performance properties. A process for repairing a vehicle body is provided using ambient conditions alone or in combination with thermal source to aid in cure after applied to the vehicle body in need of repair.

(METH)ACRYLATED COMPOUNDS BASED ON RECYCLED PET

The present invention relates to a process for preparing a polyester (meth)acrylate resin (I), said process comprising the steps of: (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; (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; (c) Reacting the polyester polyol B with (c) at least one (meth)acrylating compound to provide a (meth)acrylated compound (I), wherein the weight ratio of fatty acid (b 1) 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 %. 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.
