Claims
- 1. A method of making a hot-melt adhesive coated article comprising fusing a composition comprising a blend or sequential polymerizate of:
- (A) from about 5 to about 95 parts by weight of an addition copolymer having a T.sub.g in the range of from 0.degree. to -85.degree. C. comprising:
- (1) from about 85 to about 99.5 parts by weight of a monomer or monomers selected from an alkyl (C.sub.2 -.sub.18) or alkoxyalkyl acrylate and
- (2) from about 0.5 to about 15 parts by weight of an ethylenically unsaturated amine, carboxylic acid or sulfonic acid or mixtures thereof with
- (B) from about 5 to about 95 parts by weight of an addition copolymer having a T.sub.g in the range of from about 20.degree. to about 150.degree. C. comprising:
- (1) from about 95 to about 99.5 parts by weight of a monomer or monomers of the formula: ##STR4## wherein R is hydrogen or methyl and R.sup.1 is lower alkyl, lower cycloalkyl or isobornyl and
- (2) from about 0.5 to about 15 parts by weight of an ethylenically unsaturated amine, carboxylic or sulfonic acid or mixtures thereof.
- said components being compatible, one of the polymers A and B having acid groups and the other having amine groups, applying the molten material to the article, and cooling the coated article.
- 2. The method of making a pressure sensitive adhesive coated article in accordance with claim 1 in which the composition contains from about 15 to about 30 parts by weight of copolymer (B).
- 3. The method of claim 1 for making a non-tacky adhesive coated article in which said composition contains greater than about 30 parts by weight of copolymer (B).
- 4. The method of making a laminate comprising the step of laminating the article made by the method of claim 1 to another material.
- 5. The method of making a laminate from a coated article in accordance with claim 2 comprising the step of laminating the article to another material.
- 6. The method of making a laminate utilizing the adhesive coated article made by the method of claim 3, comprising the step of laminating the article to another material.
