A process for producing poly(1,3-propylene terephthalate) from the reaction of either terephthalic acid or a lower dialkyl ester of terephthalic acid and 1,3-propanediol and polymerization of the monomer produced therefrom using a novel catalyst system. The novel catalyst composition includes employing an effective catalytic amount tin in the polycondensation reaction. Using the catalyst system and Hostaperm® pigments allows for the production of poly(1,3-propylene terephthalate) having yellowness of less than 4 and an IV of at least 0.80 dl/g.

Compositions, methods, apparatuses, kits, and combinations are described for permanently or temporarily re-designing, decorating, and/or re-coloring a surface. The compositions useful in the present disclosure include a decor product that is formulated to be applied and affixed to a surface. If desired, the decor product may be substantially removed from the surface before being affixed thereto. If a user desires to remove the decor product, the decor product is formulated to be removed by a number of methods including, for example, vacuuming, wet extraction, chemical application, and the like. If the user desires to affix the decor product to the surface in a permanent or semi-permanent manner, the decor product may be affixed to the surface by applying energy thereto in the form of, for example, heat, pressure, emitted waves, an emitted electrical field, a magnetic field, and/or a chemical. The decor product may also be utilized in the form of a kit or in conjunction with a design device, such as a stencil, to control the application of the decor product to create, for example, a pattern on the surface.

A binder composition for thermosetting powder paints comprising (i) a polymer that is capable of reacting with epoxy groups and (ii) a crosslinker that contains epoxy groups, wherein the crosslinker comprises at least one C5 to C26 linear or branched aliphatic chain with the proviso that epoxy groups are carried on at least one aliphatic chain. In order to function as a crosslinker the amount of oxirane-oxygen originating from the crosslinker in the binder composition is higher than 0.1 meq/gram. The crosslinker is, for example, an epoxydized oil, a modified epoxydized oil or an epoxydized alkyd resin. A powder paint comprising the binder composition can contain a suitable catalyst and, optionally, an additional curing agent.
