Claims21
Composition comprising a polymer prepared by reacting a polyol having, per polymer molecule, at least one repeat unit of the formula:
- ##STR2## said polyol further having repeat units containing residual carbon-carbon double bonds;
- wherein A is absent or represents a radical derived from a pendant unsaturated hydrocarbon portion of a monomer of the polymer molecule and B represents hydrogen or together with A represents a radical derived from a pendant portion of an unsaturated monocyclic, bicyclic or tricyclic hydrocarbon, and wherein said polyol is derived from a hydroformylated polyolefin wherein said polyolefin has a level of unsaturation of from one C.dbd.C per polymer molecule to about one C.dbd.C per 4 carbon atoms prior to hydroformylation of said polyolefin, with a compound selected from the group consisting of dicarbonates, dicarboxylic acids, derivatives of dicarboxylic acids, and mixtures thereof, under suitable reaction conditions in the presence of a suitable catalyst wherein said derivatives of dicarboxylic acids are selected from the group consisting of dicarboxylic acid chlorides and anhydrides.
Composition comprising an adduct obtained by sequentially hydroformylating an olefinic polymer containing a level of unsaturation of from one C.dbd.C per polymer molecule to about one C.dbd.C per 4 carbon atoms under conditions which produce an aldehyde-containing polymer containing residual carbon-carbon double bonds and essentially free of hydroxyl groups, then subjecting said aldehyde-containing polymer to reduction conditions to produce a polyol containing residual carbon-carbon double bonds, and then reacting said polyol under suitable reaction conditions with a compound selected from the group consisting of dicarbonates, dicarboxylic acids, derivatives of dicarboxylic acids, and mixtures thereof wherein said derivatives of dicarboxylic acids are selected from the group consisting of dicarboxylic acid chlorides and anhydrides.
Method of preparing polymers comprising hydroformylating an olefinic polymer containing level of unsaturation of from one C.dbd.C per polymer molecule to about one C.dbd.C per 4 carbon atoms under conditions which produce and aldehyde-containing polymer containing residual carbon-carbon double bonds and essentially free of hydroxyl groups, then subjecting said aldehyde-containing polymer to reduction conditions to produce a polyol containing residual carbon-carbon double bonds, and then reacting said polyol under suitable reaction conditions with a compound selected from the group consisting of dicarbonates, dicarboxylic acids, derivatives of dicarboxylic acids and mixtures thereof wherein said derivatives of dicarboxylic acids are selected from the group consisting of dicarboxylic acid chlorides and anhydrides.
