A stable, aqueous composition containing a crosslinked, nonionic, amphiphilic polymer capable of forming a yield stress fluid in the presence of a surfactant is disclosed. The yield stress fluid is capable of suspending insoluble materials in the form of particulates and/or droplets requiring suspension or stabilization.

Surfactant responsive emulsion polymerized micro-gels

The invention relates to a method for improving the foaming and/or yield value properties associated with surfactant containing compositions comprising at least one anionic surfactant, the method comprises combining an effective amount of at least one nonionic, amphiphilic polymer with at least one anionic detersive surfactant in combination with an optional surfactant selected from amphoteric surfactants, nonionic surfactants and combinations of two or more thereof. The at least one nonionic amphiphilic polymer is prepared from a free radically polymerizable monomer composition comprising at least one hydrophilic monomer and at least one hydrophobic monomer, wherein said hydrophilic monomer is selected from a N-vinyl lactam and wherein said hydrophobic monomer is selected from a vinyl ester of a C-Ccarboxylic acid or at least one monomer selected from a C-Calkyl (meth)acrylate an associative monomer, a semi-hydrophobic monomer, or mixtures thereof, and an optional crosslinking monomer.

Foaming performance in cleansing compositions through the use of nonionic, amphiphilic polymers

A process for preparing a composition by free-radical polymerization of a monomer composition comprising: a) at least one ethylenically unsaturated carboxylic acid containing monomer or anhydride thereof; b) optionally at least one ethylenically unsaturated monomer different from a) but copolymerizable therewith; and c) at least one crosslinking monomer containing at least two ethylenically unsaturated groups. The monomer composition is polymerized in an organic medium having a solubilizing effect on one or more of the monomeric ingredients, but substantially none on the resulting polymer. The polymerization is conducted in the presence of a free radical forming catalyst and at least one steric stabilizing polymer polymerized from a vinyl lactam and a copolymerizable monomer selected from a short chain alkyl ester of (meth)acrylic acid, a long chain alkyl ester of (meth)acrylic acid, and combinations thereof.

Method of preparing acrylic polymers and products produced thereby

A stable, aqueous composition containing a crosslinked, nonionic, amphiphilic polymer capable of forming a yield stress fluid in the presence of a surfactant is disclosed. The crosslinked, nonionic amphiphilic polymer is prepared by dispersion polymerization in the presence of a stabilizing polymer. The yield stress fluid is capable of suspending insoluble materials in the form of particulates and/or droplets requiring suspension or stabilization.

Surfactant responsive dispersion polymerized micro-gels

The present invention provides mild cleansing and cleaning compositions and methods for mitigating irritation induced by harsh detersive surfactants. The invention relates to a method of reducing skin irritation associated with a cleansing composition comprising at least one surfactant, the method comprising combining an effective amount of at least one nonionic amphiphilic polymer with at least one detersive surfactant selected from anionic surfactants, amphoteric surfactants, nonionic surfactants and combinations of two or more thereof. The at least one nonionic amphiphilic irritation mitigating polymer is prepared from a free radically polymerizable monomer composition comprising at least one hydrophilic monomer and at least one hydrophobic monomer, wherein said N-vinyl lactam and wherein said hydrophobic monomer is selected from a vinyl ester of a C-Ccarboxylic acid or at least one monomer selected from a C-Calkyl (meth)acrylate an associative monomer, a semi-hydrophobic monomer, or mixtures thereof.

Surfactant responsive micro-gels

A high elongation, low 100% modulus composition comprises a copolymer dispersed in a continuous phase polysiloxane. The copolymer is made from high amounts of at least a monomer which is capable of forming a low Tg polymer and relatively low amounts of at least a monomer which is capable of forming a high Tg polymer. The monomer forming the low Tg polymer can be an alkyl acrylate whereas the monomers forming the high Tg polymer can be a vinyl ester, an acrylonitrile or derivatives thereof, a vinyl substituted aromatic such as styrene, an alkyl methacrylate, and the like. The composition has good adhesion to substrates as well as good viscosity aging, and can be utilized in caulks or sealants.

Polysiloxane having a copolymer dispersed therein and sealants containing the same

A polyblend of poly(vinyl chloride) ('PVC') and a copolyester ('CPE') consists essentially of three components in a structure --(MR).sub.x --(MQ).sub.y -- wherein (MR).sub.x represents an ester segment with a repeating unit of mol wt 204 or 220, (MQ).sub.y an ester segment consisting of a residue of a polyester diol, so that the CPE is non-elastomeric and has a m p in the range from above 170.degree. C. to about 220.degree. C. Then the CPE provides a limited plasticizing function in PVC when the CPE is used in the range from about 30 to about 70 parts by wt based on 100 parts of the polyblend. The lack of a typical plasticizing function is evidenced by a relatively flat modulus curve, preferably one having a slope less than 1.2.times.10.sup.5 psi per unit weight of PVC in the polyblend. A glass reinforced composite of from about 30 to 70 parts by wt PVC and from 30 to about 50 parts by wt of CPE provides a HDT which is greater than might be expected by directly proportioning the effect of the glass fibers in reinforced PVC, and reinforced CPE; the tensile strength of the reinforced composite is greater than 10,000 psi. The crystallinity of the CPE is such that it has essentially no extensibility, a flexural modulus of 3.8.+-..times.10.sup.5 psi and limited miscibility in the PVC. The limited miscibility is responsible for the unique morphology of the polyblend.
