After the esterification catalyst has been neutralised, the residual acrylic or methacrylic acid is reacted with an epoxide compound containing at least two epoxide groups per molecule. The entrainer is then removed by distillation together with residual acrylic or methacrylic acid. The invention also relates to the process for the preparation of the polyester (meth)acrylates and to the use of these polyester (meth)acrylates in radiation-curable coating compositions.

Dual thermal and ultraviolet curable powder coatings

Opaquely pigmented or thick filmed powder coatings for heat sensitive substrates, such as wood, wood composites, for example, medium density fiber board, and plastics, that can be fully cured, especially near the substrate, through the incorporation of a dual cure system in the powder comprising a thermal initiator, such as a peroxide, along with a UV initiator. The UV initiator cures the surface, while the thermal initiator cures at the substrate. Surprisingly, virtually no pregelation occurs during the heated melt and flow out step prior to UV curing. Consequently, the hardened film finish formed on the surface exhibits exceptional smoothness which is comparable to that of traditional UV curable powders. The hardened film finish is also fully cured throughout and exhibits exceptional adhesion to the substrate which cannot be achieved with traditional UV curable powders that have been pigmented. Although the dual cure system includes a thermal aspect, these powder coatings are especially suited for coating heat sensitive substrates. The dual thermal and UV curable powders still cure at significantly lower temperatures and significantly faster rates than traditional heat curable powders to make them safe for coating heat sensitive substrates.

The solubilizing group is a non-polar group, preferably an aliphatic group having at least four carbon atoms, covalently bonded to A1 and/or A2. The metal ion is a divalent ion of a metal selected from the group of manganese, cobalt, copper, lead, zirconium, iron, lanthanium, cerium, vanadium, and calcium or a trivalent ion of a metal selected from the group of manganese, cobalt, lead, zirconium, iron, lanthanium, cerium, and vanadium, combined with a monovalent counterion.

Photocurable resins and their use

Triblock copolymers and hydrogels thereof

The invention provides methods for the formation of thermo-reversible hydrogels from triblock copolymers of poly(ethylene glycol) and poly(α-benzyl carboxylate-ε-caprolactone) (PBCL-PEG-PBCL) prepared by bulk and solution polymerization. PBCL-PEG-PBCLs prepared at fixed PBCL to PEG ratios but different polymerization times were characterized for their average molecular weights, molar-mass disparity and intrinsic viscosity using 1 H NMR and gel permeation chromatography (GPC). The results indicated a copolymer of high molecular weight population with elevated intrinsic viscosity. The size and proportion of this population grew as a function of polymerization time. The formation of this high molecular weight PBCL-PEG-PBCL population can be attributed to non-linear architecture caused by partial cross-linking of the PBCL segment during the polymerization reaction. At least about 40% mole concentration of the high molecular weight PBCL-PEG-PBCL was required for thermo-reversible micellar aggregation in aqueous media and hydrogel formation.
