摘要： The alkali metal, ammonium and alkanol amine salts of polymeric acetal carboxylates are stable detergent builders and chelating agents. Now, in the improved process of the present invention for preparing an acetal carboxylate polymer wherein a glyoxylate ester and a polymerization initiator are brought together under polymerization conditions and a chemically stable end group is added to the termini of the resulting polymer to stabilize the polymer against rapid depolymerization in alkaline solution, the improvement comprises contacting the resulting polymer in the presence of an acid catalyst with a sufficient amount of an acetal having 3 to 20 carbon atoms to stabilize the resulting polymer against rapid depolymerization in alkaline solution, and an agent to remove liberated alcohol.

摘要： The alkali metal, ammonium and alkanol amine salts of acetal carboxylate polymers are known to be stable detergent builders and chelating agents which depolymerize in acid media making the polymer fragments more readily biodegradable in waste streams. Now, according to the present invention, the hydrolytic stability of an acetal carboxylate polymer can be controlled by bringing together under polymerization conditions an ester of glyoxylic acid and a polymerization initiator and adding to the termini of the resulting polymer end groups having substituents which are selected to be more electron withdrawing as the desired hydrolytic stability increases.

摘要： The alkali metal, ammonium and alkanol amine salts of polymeric acetal carboxylates are stable detergent builders under laundry use conditions, but depolymerize in acid media, making the polymer fragments more readily biodegradable in waste streams. Now, in the improved process of the present invention for preparing an acetal carboxylate polymer wherein an ester of glyoxylic acid and a polymerization initiator are brought together under polymerization conditions and a chemically stable end group is added to the termini of the resulting polymer to stabilize the polymer against rapid depolymerization in alkaline solution, the improvement comprises adding to the resulting polymer a sufficient amount of an alkali metal hydride, preferably sodium hydride, and a dialkyl sulfate having 1 to about 20 carbon atoms in each alkyl group, preferably dimethyl sulfate, to add to the termini of the resulting polymer an alkyl group derived from the dialkyl sulfate.

摘要： Terminal olefin is prepared by bringing together (1) a compound having the formula ##STR1## wherein Cp is a .pi.-cyclopentadienyl radical, R is terminal alkyl and X is an essentially non-interfering monovalent entity, and (2) a mono-olefin having a carbon skeleton different from that of R under reaction conditions to displace R from (1) by (2). This process is especially useful in isomerization of internal olefins to the corresponding terminal olefins.
