Abstract:
An adhesive composition including an etchant for a hard tissue surface, at least one multifunctional crosslinkable (meth)acrylate monomer with a functionality greater than 4, and water. The adhesive composition is a water-in-oil emulsion.
Abstract:
The present invention concerns a waterborne copolymer dispersion comprising at least one alkenyl functional dendritic polymer being copolymerized to the polymer backbone of at least one homo or copolymer obtainable by polymerization, such as emulsion polymerization, in an aqueous medium of at least one at least one polymerizable allyl, vinyl, maleic or diene monomer. The dendritic polymer is built up from a dendritic core polymer and at least one alkenyl functional compound bonded to the core polymer. In a further aspect the present invention concerns the use of said copolymer dispersion.

Abstract:
The present invention provides compositions and methods for sealing a wound and preparing a lens. The methods of the invention utilize dendritic macromolecules formed by treating a dendritic compound with light or a linking compound. In certain instances, the dendritic compounds have a lysine-, cysteine-, isocysteine-residue or other nucleophilic group attached to the periphery of the dendrimer: Addition of a compound containing two or more electrophilic groups such as aldehydes, activated esters, or acrylates to the lysine-, cysteine-, or isocysteine-capped dendrimers produces a polymeric compound that can form a seal or a lens. Another aspect of the invention relates to a method of treating disease using the pharmaceutical compositions of the invention. Other aspects of the invention relate to kits for sealing a wound or preparing a lens, delivery devices, and methods for controlling the polymerization of a hydrogel system.
Abstract:
Primers for cyanoacrylate adhesives which are based on compounds having multiple amine groups thereon ("multi-amines") which have at least three secondary or tertiary amine groups, at least one of which is a tertiary amine group. The multi-amine compounds are characterized by having thereon at least three terminal and/or pendant aliphatic hydrocarbon groups of at least 4 carbon atoms in length. Such primers give substantially improved bond strengths to cyanoacrlylate adhesive bonded assemblies comprising a polyolefin substrate such as high density polyethylene, LDPE or polypropylene. The multi-amine may have a cascade, dendrimer, hyperbranched or comb-like structure.

Abstract:
The present invention relates to hyperbranched polyaspartate esters containing repeating structural units corresponding to the formula I and/or II The present invention also relates to a process for the preparation of these hyperbranched polyaspartate esters by self condensing, via a transesterification reaction, at least a portion of the hydroxy and ester groups of the hydroxy aspartates corresponding to the above formula at a temperature of 60 to 240°C to form hyperbranched polyaspartate esters and eliminating alcohols having the formula R 1 -OH and/or R 2 -OH.
