Abstract: Novel modifying agents contain a sharply-melting crystalline polymer ingredient, preferably a side chain crystalline (SCC) ingredient, and an active chemical ingredient. Such modifying agents, especially when in the form of particles, can be placed in contact with a matrix, will not modify the matrix below the crystalline melting point Tp, but will rapidly modify the matrix above Tp. The active chemical ingredient can react with the matrix, catalyze a reaction of the matrix, or inhibit a reaction of the matrix. Particularly useful compositions are polymer precursors which are storage-stable at low temperatures but which are rapidly converted to crosslinked resins when heated to temperatures above Tp, optionally in the presence of light.

Abstract: In an embodiment, the present invention is directed to notifying a user of web content elements maintained by an information site. The notification may occur by processing web content queries from a user. First web content elements communicated in response to the queries and selected by the user may be associated with the user via a user profile. The first web content elements may be compared against second web content elements to identify related web content elements. The user may then be notified of the related web content elements.

Abstract: A tool that facilitates aligning members with respect to each other and an object is described. The tool includes a roll of material including an upper and a lower side. The material lower side includes adhesive material that enables the tool to be affixed to the object. The material upper side includes a plurality of reference markings arranged in a cyclic pattern that is repeated along an entire length of the tool. More specifically, adjacent reference markings are a pre-determined length apart that is selected depending on a desired alignment of the members to be aligned.

Abstract: A controlled release and delivery system for a hydrophobic, water sensitive herbicide is produced by:(a) dissolving the herbicide in a volatile water-immiscible solvent;(b) introducing the solvent containing the herbicide dissolved therein to a latex dispersion comprising an aqueous continuous phase and polymeric discrete phase;(c) agitating the resultant mixture until the polymeric particles of the discrete phase absorb the herbicide; and(d) removing the solvent from the resultant mixture at reduced pressure.

Abstract: Composite materials useful as hard tissue prosthetics comprising synthetic biodegradable polymers and unsintered calcium phosphate biomaterials optionally porositized by pore-forming agents are described. The composite materials may be ground and blended with a compatible water soluble pore-forming agent and then molded to form dense, shaped objects which may be made porous by leaching out said water soluble pore-forming agent. The composites may be used as hard tissue prosthetics either alone or in conjunction with conventional prostheses.

Abstract: An in situ polymerization process is disclosed whereby an .alpha.-amino acid N-carboxyanhydride is blended intimately and efficiently with one or more calcium phosphate biomaterials. The polymerization proceeds at ambient temperature and pressure without the need for initiators or surface modification of the calcium phosphate biomaterials. The resulting composite material may subsequently be ground and blended with a compatible water soluble pore-forming agent and then molded to form dense, shaped objects which may be made porous by leaching out said water soluble pore-forming agent. The resulting shaped objects may then be used as hard tissue prosthetics either alone or in conjunction with conventional prostheses.

Abstract: The present invention is directed to mineral filled .alpha.-amino acid polymer composite materials. The composite materials are prepared by the in situ polymerization of an .alpha.-amino acid N-carboxyanhydride in the presence of mineral fillers which are optionally surface-modified with a partially hydrolyzed polyoxazoline prior to said polymerization. Composite materials prepared in this manner consist of an intimate mixture of polymer and mineral filler which may be optionally blended with a crosslinking agent and then molded to produce smooth, hard homogeneous materials that are water and oil resistant and have good heat distortion properties.
