Abstract
Compositions suitable for bonding fibrous substrates such as air-laid paper mats comprise hydrophilic air-curing polymer and a thermoplastic polymer latex.
Claims15
A polymer composition having a water wicking time of less than thirty seconds comprising:
- (A) from 5 to 95 percent by weight of a thermoplastic polymer in the form of solid, stably dispersed latex particles;
- and
- (B) from 95 to 5 percent by weight of a liquid hydrophilic polymer having a backbone comprising at least one segment with the formula ##STR12## wherein A is a moiety terminating in the residue of an active hydrogen-containing group selected from the group consisting of alcoholic hydroxyl, thiol, amide, carboxylic acid and secondary amine with an active hydrogen removed, E is a moiety containing a radical having an activated olefinic unsaturation either .alpha.,.beta. or .beta.,.gamma. to the activating group;
- n is the number of adjacent segments having this formula and n and m are integers and are each at least one provided that where either is less than 4, the other is at least four;
- all weights being based on the total polymer weight in the composition.

A polymer composition having a water wicking time of less than 10 seconds comprising:
- (A) from 20 to 80 percent by weight of a thermoplastic polymer selected from the group consisting of poly-(ethylene/vinyl acetate), poly (ethylene/vinyl chloride) and acrylic acid ester polymers in the form of an aqueous latex;
- and
- (B) from 80 to 20 percent by weight of a liquid hydrophilic polymer obtained by the reaction of a polyol with at least 4 mols of allyl glycidyl ether per hydroxyl group in the polyol;
- all weights being based on the total polymer weight in the composition.

- n is the number of adjacent segments having this formula and n and m are integers and are each at least one provided that where either is less than 4, the other is at least four;
- all weights being based on the total polymer weight in the composition.
