A composition of matter comprising an acrylamido-acyl or methacrylamido-acyl oligomer derived from at least one nucleophilic oligomer having at least one amino-, hydroxyl-, or thiol-substituted polyoxyalkylene, polyalkyleneimine, polyester, polyolefin, polyacrylate, or polysiloxane oligomer, said nucleophilic oliogmer having a molecular weight in the range of 200 to 20,000 is disclosed. Also disclosed are free radially polymerizable monomer-containing compositions containing said oligomers as well as acrylamido- and methacrylamido-acylated polymers which are the thermal or photocured products of said oligomers. In addition, a process is disclosed for providing said acrylamido- and methacrylamido-acylated oligomers which are useful, for example, in coatings, films, printing inks, adhesives, and saturants.

A cordless rechargeable replaceable battery assembly powered drive assembly for driving orthopedic surgical instruments in which the battery has silver and zinc oxide electrodes in sodium hydroxide electrolyte to provide low voltage high current power. The switch is encased in the battery assembly, the battery cells are vented through a microporous polymeric curtain to restrict expulsion of electrolyte, a two speed transmission is provided to change drive speeds, and a brush block on the motor has contacts adapted to be connected in different combinations to change the motor rotation direction.

Orthopedic drive assembly

Azlactone-functional compounds, which are liquid above 20.degree. C., and their method of preparation from alkenyl azlactones and nucleophilic group-substituted compounds are disclosed. The azlactone-functional compounds of the invention cure in the presence of nucleophilic chain-extending or crosslinking agents to form linear or crosslinked polyamide resin systems.

Curable compositions containing azlactone-functional compounds

A hydrosilation process is dislosed for the reaction between silicon-hydrogen bonds and compounds having aliphatic carbon atoms linked by multiple bonds using as catalysts novel platinum-nitrogen complex compounds of the following classes:

Azlactone-functional compounds

A method of modifying the overall hydrophilic or hydrophobic nature of a high molecular weight free radical addition interpolymer, which is an azlactone-functional interpolymer, with a hydrophilic or hydrophobic nucleophilic compound is disclosed. Only the surface of the interpolymer can by hydrophilized or hydrophobized, as when the interpolymer is a coating, or the modification can take place throughout the entire bulk of the interpolymer.

Method of hydrophilizing or hydrophobizing polymers

A composition comprising a radiation-curable polymer, said polymer being crosslinkable and having pendant ethylenically unsaturated peptide groups is disclosed. Such polymers are useful in the field of graphic arts.

Radiation-curable polymers

A latently curable organosilicone composition is stabilized against premature gelation by the presence of an amount of an unsaturated amide that is sufficient to inhibit gelation of the composition at low, ambient or room temperature but insufficient to prevent hydrosilation at an elevated temperature.
