Problems solved by technology

The disadvantage of this modification is the creation of a uniform water film that slowly drains from the surface
As a result, these polymers lead to an increased time required to dry the treated surface

Embodiment 1

[0170] The 1 L reactor was purged with nitrogen. An initial charge of 15.5 g DADMAC (65.9%) solution, 1.3 g N,N-dimethylacrylamide, 40 mg acrylic acid (99%) solution, 1.5 g NaEDTA (10%) solution and 250 g deionized water was added to the reactor. The pH of the reaction mixture was adjusted to about 4.0 + / - 0.2 with HCl (5%) solution. The reaction was stirred at 210 rpm and heated to 100°C. A monomer charge was prepared from 6.7 g DADMAC (65.9%) solution, 54 g N,N-dimethylacrylamide, 3.25 g acrylic acid (99%) solution, 70 mg thioglycolic acid and 110 g deionized water. The pH of the feed solution was adjusted to about 4.0 + / - 0.2 with NaOH (10%) solution. Initially 5 ml of the monomer feed was added to the reactant mixture. Initiator (ammonium persulfate, 0.2 g in 20 ml of water) was introduced at a rate of 0.22 ml / min while the remainder of the monomer feed was added over 60 min. After completion of the monomer feed, the container containing the monomer feed was rinsed wit...

Abstract

The claims encompass hard surface cleaner and hard surface treatment compositions containing particular ampholytic polymers which impart not only good residua! cleaning properties but in particular give fast drying properties to the cleaning compositions. The polymers are for example terpolymers formed from diallydialkyammonium chloride, anionic monomers and N,N Cdi-C1-C8 alkyl (meth)acrylamides.

Description

[0001] This application claims the benefit of Provisional Application No. 61 / 210,635, filed March 20, 2009, which is hereby incorporated by reference in its entirety. field of invention [0002] The present invention relates to hard surface cleaner compositions comprising specific amphoteric polymers which impart not only good residue cleaning properties to the cleaning composition but also especially fast drying properties to the composition . The polymer is a terpolymer formed from diallyldialkylammonium chloride, (meth)acrylic acid and N-alkyl substituted acrylamide. Background of the invention [0003] The incorporation of various amphoteric polymers in cleaning formulations, especially hard surface cleaning formulations, is well known. Amphoteric polymers such as copolymers of diallyldialkylammonium chloride (DADMAC) and acrylic acid are known to provide various benefits to hard surface cleaners. Among the benefits described above, for example, amphoteric polymers can...
