Specifically, the particular comparative polyol mix, Example E, composed 56. 3 excess weight percent of the low-Tg copolymer associated with 20% methyl methacrylate, 15% styrene, 30% butyl acrylate, and 35% hydroxyethyl methacrylate. In Table VIII, the low-Tg copolymer used above within the polyol mix of Example 4, is referred to in Table III as Example Chemical, and the high-Tg copolymer used above within the polyol mix of Example 4, is referred in order to in Table VIII as Example Deb. Examples C and D were in comparison with the polyol blend of Example 7. The polyol blend of Example 7 comprises 61. 3% of Illustration C and 38. 7% of Instance D. White paints were prepared with these stand-alone copolymers, Examples C and D, as well as the polyol blend of Example 7. Such white paint comparative formulations had a 1/1 pigment to binder ratio, and the 1. 1/1 isocyanate group to hydroxyl group ratio. Within order to demonstrate the low viscosity achieved by technique polyol blends of the innovation over stand-alone copolymers, the log (to the base 10) of the viscosity, in centipose, because a function associated with the log (to the base 10) from the weight-average molecular weight was compared between polyol combines of the invention plus certain stand-alone copolymers.

To be able to show the compatibility of the low Tg plus high Tg copolymers when blended, samples of blended reduced Tg and large Tg copolymers had been prepared and put through Differential Scanning Calorimeter (DSC) scans at a scan rate associated with 20. 00 degrees per minute in order to establish the polyol blends provide an individual Tg. This compatibility is established from the fact that when blended, the polyol blends exhibit the single Tg. These polyol blends, when mixed with the polyisocyanate cross-linking real estate agent, provided film-forming compositions. Third, the polyisocyanate cross-linking agent will be added to a second package or container in a degree sufficient to yield an isocyanate group to hydroxyl team equivalent-weight ratio associated with about 0. 8/1. 0 to regarding 1. 3/1. zero in the final coating. As used herein, the hydroxyl group equivalent pounds is dependent upon dividing the number 56, 104 by the hydroxyl number; and the isocyanate group equivalent weight is identified by dividing the quantity 4, 200 with the wt. -% -NCO (i. e., isocyanate) moiety that will be present in the isocyanate moiety-bearing agent or ingredient. The term "grind" as used herein, so that as utilized by others in the art, is recognized to mean color dispersion.

The term "binder" as utilized herein is recognized to mean the particular single acrylic copolymer or maybe the polyol blend, whichever is utilized. First, a pigmented paste, either associated with one of the low-Tg or high-Tg polymer copolymers (alone), or even of the polyol blend, is prepared by mixing the color with the copolymer or polyol blend in a pigment-to-binder bodyweight ratio of about 1: 1 in order to about 5: one, to provide a grind. Enough color was used in order to yield a 1/1 pigment to binding ratio in the last coating. For this was additional 3. 66 grms of the 0. 1% solution of dibutyl tin dilaurate prompt in methyl n-amyl ketone and two. 56 grams of a 28/72 parts-by-weight ratio of a commercially-available polyether-modified methyl alkyl polysiloxane (known because "BYK-320", and sold by BYK Chemie)/MAK solution, like a silicon. Accordingly, titanium dioxide pigment was dispersed in a methyl n-amyl ketone (MAK) solution of every from the polyol blends of Examples four, 5, and six, as well as the stand-alone copolymers of Examples The and B upon a Cowles mixing machine at 2000 in order to 2500 rpm regarding 20 to twenty five minutes.

Butyl acrylate is a monomer used to produce poly(tert-butyl acrylate) (PtBA) polymers and copolymers, and poly(acrylic acid) polyelectrolyte brushes. The particular monomer can end up being used to synthesize Poly(t-butyl acrylate). Even though the invention provides been described in detail by referring to certain preferred embodiments, it can be understood that various modifications can be made within the spirit and scope of the invention. The invention is just not to be limited except like set forth in the following claims. SHORT DESCRIPTION OF THE PARTICULAR DRAWINGS The sketches comprise a graph and scans from the following good examples. Table XI presents the parts-by-weight preparations of the mixes of Examples 9-20. For example, 27. 22 parts by weight of a low Tg polymer-bonded copolymer (identified immediately above and Table X as Low Tg Copolymer "I") were combined with seventy two. 78 parts by weight of a high Tg acrylic copolymer (identified immediately above and inside Table X while High Tg Copolymer "VI").
