Controlled release biodegrading microcapsules comprising polypeptide chains.

Biodegradable, controlled release microcapsules

A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms.

Controlled release microcapsules

The invention discloses a microencapsulated phase change material having a specific Thermal Efficiency Index (TEI).TEI=&#x3b1;()*&#x3b2;()*&#x3b3;()*&#x3b4;(@180)*&#x2208;()The problem of achieving effective and efficient microencapsulated phase change material can be solved to yield a commercially useful material having the described combination of physical and chemical characteristics based on the parameters described in the specification. Microcapsules according to the invention are highly effective at delivering enhanced thermal performance as compared to conventional microcapsules.

Encapsulates

High strength, high integrity microcapsules containing a hydrophobic core material wherein said microcapsule walls are formed of copolymers of select monomers through a multistep oil-in-water emulsification polymerization process.

High strength microcapsules

A coated paper with enhanced properties and/or lower cost can be obtained by using a coating that contains a binder and stanchion-encapsulated titanium dioxide. The stanchion-encapsulated titanium dioxide can provide the same or similar brightness, gloss, and/or opacity while using less titanium dioxide.

Coated paper

The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

Benefit agent containing delivery particle

A paint composition, which comprises a stanchion-encapsulated pigment such as titanium dioxide, can provide enhanced paint quality with reduced cost.

Paint with encapsulated solid particles

Disclosed are encapsulating methods and encapsulated products. A payload material may be encapsulated within a wall material. The carrier material and payload material form a combination that is at least substantially solid at room temperature but that is sufficiently fluid at milling temperature to permit milling and subsequent encapsulation. The payload material may be, for instance, a bitter tasting material. In some embodiments, the microcapsules will serve a taste masking function. In other embodiments, the microcapsules may be used where a slow release of the payload material is desired.

Encapsulation

The invention teaches an encapsulated curable adhesive composition especially adapted for use as a structural adhesive. The adhesive composition enables formation of a thin layer reactive composition of microcapsules and a two-part curative. The adhesive composition comprises a first population of microcapsules encasing a monomer and a first-part curative comprising an initiator. The adhesive composition further comprises a second-part curative. The second-part curative comprises an activator and a catalyst. At least the activator of the second-part curative is preferably encapsulated in a second population of microcapsules. The catalyst and the second population of microcapsules can be dispersed in a binder material, along with the first population of microcapsules. The first population of microcapsules contain encapsulated within the core a monomer having a Tg 35&#xb0; C. or less and the first-part curative. The first population microcapsules contain encapsulated within the core a monomer having a Tg 35&#xb0; C. or less along with the first-part curative. The encapsulated monomer and first-part curative constitute a blend which is a free flowing liquid having a viscosity of less than 500 Cp (milliPascal-second), and more preferably less than 10 Cp (milliPascal-second). The first population of microcapsules with first-part curative, and a second-part curative and second population of microcapsules are dispersed in a binder material. Reactive contact of the monomer and first-part curative with the second-part curative is affected by exuding the respective capsule contents into reactive contact through breakage of the microcapsules such as an interference fit of the substrate or substrates to which the composition is applied.
