Encapsulation of and binding to pegylated bioactive molecules via functionalized comb, block, branched type polymers formed by nitroxide mediated controlled radical polymerization is disclosed.

Polymer encapsulation and/or binding

The present invention relates to acrylic block copolymers synthesized by a controlled free-radical process, and their use as low temperature flow modifiers in oil-based compositions. They are especially useful in modifying the low temperature flow behavior in lubricating oils. The acrylic copolymers are especially useful as pour point depressants in lubricating oil.

Acrylic block copolymer low temperature flow modifiers in lubricating oils

The present invention relates to the use of poly acrylic and/or methacrylic macroinitiators in the free radical addition reaction of vinyl aromatic monomers to improve the properties of the resulting copolymer and/or composite. More particularly, the present invention relates to the production of poly acrylic and/or poly methacrylic macroinitiators having nitroxyl end groups. Using such macroinitiators in the free radical addition reaction of vinyl aromatics such as polystyrene compatibilizes the acrylic monomer in the vinyl aromatic matrix thereby improving the properties of the resulting polymer.

Methods of producing vinyl aromatic polymers using (meth)acrylic macroinitiators

The invention relates to an amphiphilic multiblock copolymer capable of forming non-covalent crosslinks. The non-water soluble copolymer, having a hydrophilic middle block and hydrophobic end blocks, has a high water transmission or permeation. The copolymer can be used in applications requiring absorption and/or transmission of fluids, the preferred fluids being water or hydrophilic liquids such as glycerin, glycols, and alcohols. One specific use of the amphiphilic multiblock copolymer is as a hydrogel material.

Amphiphilic block copolymers

The present invention relates to acrylic block copolymers synthesized by a controlled radical process, and their use as thickeners in oil-based compositions. The acrylic copolymers are especially useful as viscosity index improvers in lubricating oil.

Thermally stabilized initiator compositions comprising:

Stabilized organic peroxydicarbonate compositions

Processes for the controlled radical polymerization of acrylic and related polymers to produce improved low VOC coating materials, or powder coating compositions, the novel polymers so produced, the catalyst systems employed, processes for application of the improved coatings, coatings so produced and objects coated on at least one surface with the novel coatings are disclosed.

High-solids coatings resins via controlled radical polymerization

Use of OO-t-amyl-O(2-ethylhexyl)monoperoxycarbonate as a curing catalyst for bulk molding compounds (&ldquo;BMC&rdquo;s) and sheet molding compounds (&ldquo;SMC&rdquo;s) is provided.

Curing catalyst

Stabilized organic peroxydicarbonates compositions

In the process according to the invention for the aqueous suspension polymerization of vinyl chloride, alone or as a mixture with another vinyl monomer, the polymerization initiator comprises at least one compound chosen from dialkyl peroxydicarbonates, peroxy-tert-alkanoates and diacyl peroxides and use is made, as agent for halting the polymerization, of a mono- or disubstituted hydroxylamine. The resins thus obtained exhibit improved color and heat stability.
