Abstract: This invention relates to a process for preparation of non-crosslinked linear monofunctional and telechelic difunctional unsaturated polymers wherein the functional groups are reactive terminal groups other than vinyl groups. The average functionality number of the monofunctional unsaturated polymers is at least 0.7, as determined by nuclear magnetic resonance spectroscopy (NMR). The average functionality number of the telechelic difunctional polymers is at least 1.7, as determined by NMR. Monofunctional olefins and difunctional olefins are reacted with cyclic olefins or unsaturated polymers to prepare difunctional polymers. The process is substantially free of side reactions comprising double bond migration and cyclization.

Abstract: The compounds of this invention are bicyclic, tricyclic, azabicyclic and azatricyclic amides represented by the formula: ##STR1## wherein: R.sub.1 and R.sub.2 are the same or different members of the group consisting of halo, phenyl, substituted phenyl and a ##STR2## group wherein n, m and p are independently an integer of from 1 to 8 provided that n+m+p is equal to or less than 10; X is thio, sulfinyl or sulfonyl; Alk is straight or branched chain lower alkylene; R.sub.3 is selected from the group consisting of a bicycloalkylamino, tricycloalkylamino, azabicycloalkyl, azatricycloalkyl, azabicycloalkylamino, azatricycloalkylamino or dicycloalkylamino. The compounds are useful as anti-inflammatory and anti-allergy agents.

Abstract: A surgeon's glove which is free of mold release powder of mineral origin. The glove is "talc free" and contains on a surface a lipo compound and a surfactant for such lipo compound. The glove is manufactured by a process which includes coating a glove form with a coagulant containing the lipo compound and its surfactant in a dispersion which stay with the glove after it is stripped from the mold providing a mold release surface for such glove.
