摘要:
Disclosed is a method for making nongelled addition polymers, especially carbamate functional additional polymers from linear unsaturated anhydrides. The method comprises reacting an unsaturated linear anhydride with an active hydrogen compound to provide two monomers comprising polymerizable C═C bonds, at least one of said monomers comprising an acid functional group; polymerizing the polymerizable C═C bonds of the two monomers to provide an acid functional polymerization product; and reacting the acid functional polymerization product with an epoxy functional compound to provide a nongelled addition polymer, wherein the disclosed method does not include a step comprising the physical removal of any acid functional monomers or polymerization products. Also disclosed is a curable coating composition containing the resulting carbamate functional polymer, as well as a coated substrate comprising a cured film resulting from the application and curing of the disclosed curable coating composition.
摘要:
Disclosed is a method for making nongelled functional addition polymers from linear unsaturated anhydrides. The method subjects a linear unsaturated anhydride compound, an active hydrogen compound, and an epoxide compound to reaction conditions such that each of the following three reactions occur: (i) polymerization of polymerizable C═C bonds, (ii) ring opening of an anhydride functional group of the linear unsaturated anhydride compound by the active hydrogen compound to create an acid functional group, and (iii) reaction of the acid functional group resulting from the anhydride ring opening with the epoxide compound. At the time of reaction (iii), the acid functional group resulting from the anhydride ring opening may be selected from an ethylenically unsaturated monomer, a polymer, or both. In one embodiment, the method does not include the physical removal of any acid functional monomers or polymerization products. Also disclosed are a curable coating composition and a coated substrate.

The invention provides carbamate-functional resins and coating compositions incorporating said resins that have improved adhesion with respect to subsequently applied films or coatings. More particularly, the invention relates to carbamate-functional addition polymers having at least 250 grams of polymer per carbamate group which are made with less than 35 percent by weight of nonfunctional monomers, preferably with less than 20 percent by weight and most preferably from 0 to less than 10 percent by weight, based on the total weight of the polymer. The invention further provides a method of making a carbamate-functional polymer and carbamate-functional polymers made by the claimed method. Finally, the invention provides a method for improving the adhesion of a first coating composition to a subsequently applied material as well as a method of making a composite comprising a coated substrate, an adhesive composition, and a glass having at least one surface.

A method for reducing the molecular weight of aminoplast compounds, the aminoplast compounds obtained thereby, and coating compositions containing said aminoplast compounds are provided. The reduced molecular weight aminoplasts are obtained by reacting (a) an aminoplast compound, having a total number (y) of reactive substituents on the amino nitrogens of the aminoplast, where y=(E.times.M) and E=equivalents per mole of aminoplast and M=total number of moles of aminoplast, wherein the reactive substituents are selected from the group consisting of --NH, alkylol, alkoxy, alkoxyalkyl, and mixtures thereof and(b) at least one carbamate compound selected from the group consisting of unsubstituted and substituted primary carbamate compounds, unsubstituted and substituted secondary carbamate compounds and mixtures thereof, in the presence of primary or secondary alcohols, at temperatures under 150.degree. C., and at pressures ranging between atmospheric pressure and 20 atm pressure, to form a functionalized aminoplast compound, wherein at least one and up to (y-1) of the amino substituents on the aminoplast are substituted with the carbamate functionality.
摘要:
A carbamate or terminal urea functional vinyl polymer is prepared by reacting a compound having an hydroxyl group and a carbamate group, terminal urea group, or a group that can be converted to a carbamate or terminal urea group, with a cyclic carboxylic acid anhydride group to form an ester bond and a free acid group from the anhydride; and reacting the free acid group with a compound having an epoxide group. The cyclic carboxylic acid anhydride group may be pendant to a vinyl polymer, or one of the compound having an hydroxyl group, a compound having the cyclic carboxylic acid anhydride group, and the compound having an epoxide group may have polymerizable ethylenic unsaturation that is polymerized, optionally with one or more copolymerizable monomers to form a vinyl polymer. When the compound having an hydroxyl group has a group that can be converted to a carbamate or terminal urea group, the group is converted to the carbamate or terminal urea group after step (a). The carbamate or terminal urea functional vinyl polymer may be included in a coating composition. The coating composition may be applied to a substrate and cured to form a cured coating on the substrate.
