Abstract
The present invention provides water-borne adhesives and adhesive emulsions comprising: (1) 25 to 55 weight percent of a grafted polyolefin comprising the reaction product of (i) a polyolefin, (ii) an ethylenically unsaturated monomer having functionality capable of reacting with an amino group and (iii) an amino carboxylic acid; (2) a minor amount up to 10 weight percent of a surfactant; and (3) 55 to 80 weight percent water.
Claims20
An adhesive composition comprising the reaction product of:
- (a) a polyolefin homopolymer or copolymer modified by grafting thereto an unsaturated monomer bearing a functional group capable of reacting with an amino group;
- with (b) an amino carboxylic acid compound bearing at least one primary or secondary amine groups, which are reactive with the functional group on said polyolefin.
An adhesive composition comprising the reaction product of:
- (a) a polyolefin homopolymer or copolymer modified by grafting thereto an amino carboxylic acid compound bearing at least one primary or secondary amine groups.
An emulsion composition comprising:
- (1) 25 to 55 weight percent of a grafted polyolefin comprising the reaction product of (i) a polyolefin, (ii) an ethylenically unsaturated monomer having functionality capable of reacting with an amino group and (iii) an amino carboxylic acid;
- (2) a minor amount up to 10 weight percent of a surfactant;
- and
- (3) 55 to 80 weight percent water.
An emulsion composition comprising:
- (1) 25 to 55 weight percent of a grafted polyolefin comprising the reaction product of (i) a polyolefin and (ii) an amino carboxylic acid;
- (2) a minor amount up to 10 weight percent of a surfactant;
- and
- (3) 55 to 80 weight percent water.
An adhesive composition comprising the reaction product of:
- (a) a polyolefin homopolymer or copolymer modified by grafting thereto a compound produced by reacting (a) an unsaturated monomer bearing a functional group capable of reacting with an amino group with (b) an amino carboxylic acid compound bearing at least one primary or secondary amine groups, which are reactive with the functional group on said unsaturated monomer.
