阅读：698发布：2024-02-02

专利汇可以提供Primer compositions comprising zinc chromate, stabilizers and acrylate polymers containing oxazolidine units专利检索，专利查询，专利分析的服务。并且Acrylic and methacrylic primer compositions are provided which comprise zinc chromate and a film-forming acrylic polymer or methacrylic polymer with oxazolidines as adhesiion promoting monomeric units and a stabilizer of the structure

WHEREIN R and R1 are each selected from the group consisting of -H, alkyl of one to four carbons and alkanol of one to four carbons, and R2 is selected from the group consisting of -H, -OH, alkyl of one to eight carbons, alkanol of one to four carbons, (CH2)nHN2 where n is 2 to 6 and -(CH2CH2NH)mCH2CH2NH2 where m is 1 to 3. The stabilizer improves viscosity stability, pigment dispersion or both.，下面是Primer compositions comprising zinc chromate, stabilizers and acrylate polymers containing oxazolidine units专利的具体信息内容。

权利要求

1. IN A COMPOSITION COMPRISING AT LEAST ONE MEMBER OF THE GROUP CONSISTING OF FILM-FORMING ACRYLIC POLYMERS AND METHACRYLIC POLYMERS HAVING ACRYLOXYALKYLOXAZOLIDINE ADHESION PROMOTING MONOMERIC UNITS DISSOLVED IN AN ORGANIC SOLVENT ALSO CONTAINING AN ADHESION PROMOTING AMOUNT OF ZNCRO4, THE IMPROVEMENT WHEREIN THE COMPOSITION CONTAINS 50 TO 400 MOLE PERCENT BASED ON THE MOLES OF OXAZOLIDINE ADHESION PROMOTING MONOMERIC UNITS OF A STABILIZER HAVING THE GENERAL STRUCTURE:

2. The composition of claim 1 wherein the adhesion promoting units in the acrylic or methacrylic polymers is 2-methacryloxyethyl-2,2-spirocyclohexyl oxazolidine.

3. The composition of claim 1 wherein acrylic polymer is a methyl methacrylate polymer of film-forming molecular weight.

4. The composition of claim 3 wherein the adhesion promoting monomeric units are present in an amount up to 5 percent by weight of the polymer.

5. The composition of claim 1 wherein stabilizer is selected from the group consisting of diethyl amine, triethyl amine, diethanol amine, 2-diethylaminoethanol and dimethylamino propylamine.

6. The composition of claim 2 wherein stabilizer is selected from the group consisting of diethyl amine, triethyl amine, diethanol amine, 2-diethylaminoethanol and dimethylamino propylamine.

7. The composition of claim 3 wherein stabilizer is selected from the group consisting of diethyl amine, triethyl amine, diethanol amine, 2-diethylaminoethanol and dimethylamino propylamine.

8. The composition of claim 3 wherein stabilizer is 2-diethylaminoethanol.

9. The composition of claim 5 wherein stabilizer is 2-diethylaminoethanol.

10. The composition of claim 4 wherein stabilizer is present in a molar amount of about 200 mole percent based on the moles of adhesion promoting monomeric units.

11. The composition of claim 9 wherein stabilizer is present in a molar amount of about 200 mole percent based on the moles of adhesion promoting monomeric units.
