摘要:
THIS INVENTION DEALS WITH NEW UNSATURATED ESTERS OF A,B-UNSATURATED CARBOXYLIC ACIDS DERIVED FROM HALOGENATED ALCOHOLS OF THE FORMULAS
HO-R-C(-X)=C(-X)-R'' AND HO-C(-X)2-C(-X)2-R''
WHEREIN R IS A DIVALENT HYDROCARBON MOIETY HAVING AT LEAST ONE AND NO MORE THAN 10 CARBON ATOMS, X IS A MEMBER SELECTED FROM THE CLASS OF BROMINE AND CHLORINE, AND R'' IS A MEMBER SELECTED FROM THE CLASS OF HYDROGEN, X AND A MONOVALENT HYDROCARBON CONTAINING AT LEAST ONE AND NO MORE THAN 20 CARBON ATOMS. TYPICAL ESTERS ARE THE ACRYLATES, METHACRYLATES, MALEATES, FUMARATES, ITACONATES AND CINNAMATES. THESE MONOMERS POSSESS FIRERETARDANT PROPERTIES AND ARE USEFUL FOR THE SYNTHESIS OF POLYMERS AND COPOLYMERS.
WHEREIN R REPRESENTS H AND CH3, THE NUMBER OF SUCH REPEATING UNITS IS AT LEAST 2, AND R'' REPRESENTS H, A HYDROCARBON GROUP CONTAINING ONE TO TWELVE CARBON ATOMS AND HALOGENATED DERIVATIVES THEREOF. THE PROCESS ALLOWS THE FACILE AND ECONOMICAL SYNTHESIS OF A LARGE NUMBER OF CROSSLINKABLE POLYMERS.

Triazine compounds are disclosed which are derivatives of symmetrical triazine having one radical of the structure THERE BEING AT LEAST ONE METAL COORDINATING GROUP OF THE STRUCTURE -CHR4COOM, wherein M, Z, R2, R3 and R4 are as defined hereinafter. These compounds are useful for coordinating with and removing metals from solutions or for preparing resins capable of removing metals from solutions.
摘要:
The esters disclosed herein comprise polymerizable acrylic esters of the halogenated acetylenic alcohols, WHEREIN R represents hydrogen preferably or a monovalent hydrocarbon containing one to 10 carbon atoms, X is a halogen selected from the class consisting of chlorine and bromine, y represents an integer having a value of 1 or 2, and one n represents zero and the other n represents an integer having a value of 0 to 3, preferably zero. These acrylic monomers are useful for the preparation of self-extinguishing homopolymers and copolymers; the diesters are also particularly useful as crosslinking agents for other monomers and polymers.
摘要:
This invention relates to polymerizable acrylic esters of the halogenated acetylenic alcohols, WHEREIN R represents hydrogen and a monovalent hydrocarbon containing one to ten carbon atoms, X is a halogen selected from the class consisting of chlorine and bromine, y represents a numerical value of 1 or 2, and n represents a numerical value of 1 to 3. These acrylic monomers are useful for the preparation of self-extinguishing homopolymers and copolymers; the diesters are also particularly useful as crosslinking agents for other monomers and polymers.
IN WHICH R REPRESENTS AND CH3, RD REPRESENTS AN UNSATURATED HYDROCARBON GROUP CONTAINING 15 TO 20 CARBON ATOMS AND CONSISTING OF A TERMINAL CH3 GROUP AND AT LEAST ONE AND NO MORE THAN FOUR -CH=CH- GROUPS AND THE REMAINDER -CH2- GROUPS, AND Y REPRESENTS -OH OR R''COO-WHEREIN R'' IS A MONOVALENT HYDROCARBON CONTAINING ONE TO 20 CARBON ATOMS. THESE POLYMERS ARE MULTIPURPOSE POLYMERS AND ARE CONVERTED TO CROSSLINKED POLYMERS BY AIR DRYING OR BY RADICAL AND THERMAL INITIATION, AND BY ULTRAVIOLET AND IONIZING RADIATION.
