摘要:It relates to the field of synthetic macromolecular chemistry, and discloses a method for one-step synthesis of thiol-functionalized polyester polyols by organic catalysis. This method uses lactone monomer as reaction raw material, thiol-alcohol as initiator, and diphenyl phosphate as organic catalyst to catalyze and synthesize the thiol-functionalized polyester polyols. The present invention provides a method which is simple, inexpensive, easily controllable and environmentally friendly to prepare thiol-functionalized polyester polyols with the easily available and controllable catalyst. The method can selectively catalyze the ring opening polymerization of lactone to prepare thiol-functionalized polyester polyols using the organic catalyst.

摘要:Hydroxy sulfonic acids in general and isethionic acid (2-hydroxy ethyl sulfonic acid) in particular can be prepared at 99+% purity and good yields by the selective oxidation of a precursor hydroxy mercaptan with hydrogen peroxide. The resulting product is pure enough to be used directly in the synthesis of sulfo-acrylic esters which are finding considerable use as stabilizers in producing vinylidene chloride copolymers used for FDA approved packaging films.

标 题:Method for the synthesis of copolymers for producing polymethacrylimides
发明人：SCHERBLE JONAS; STEIN PETER; ALUPEI JULIAN C; RITTER HELMUT; SCHWARZ-BARAC SABINE
权利人:ROEHM GMBH
摘要:The invention relates to a method for producing polymethacrylimides in two steps: 1) radical copolymerization of (meth)acrylamides (A, (Me,H)HC=CHCONHR2) and alkyl(meth)acrylic esters (B) and optionally further ethylenically unsaturated monomers in the presence of an aqueous solvent. The monomers (A) include, in addition to acrylamide and methacrylamide, (meth)acrylamides that are substituted on their nitrogen group (R2<>H). The monomers (B) are the (meth)acrylic esters of secondary or tertiary alcohols, preferably tert. butylmethacrylate. 2) Thermal or catalytic reaction of the copolymers produced in 1) to polymethacrylimide or for R2<>H to N-substituted polymethacrylimides while alkenes are separated.
