Process For Preparing Ethylenically Unsaturated Isocyanurates

View page
US Patent:
41285379, Dec 5, 1978
Filed:
Jul 27, 1977
Appl. No.:
5/819352
Inventors:
Kenneth H. Markiewitz - Wilmington DE
Assignee:
ICI Americas Inc. - Wilmington DE
International Classification:
C08G 1800
US Classification:
528 49
Abstract:
Process for the preparation of ethylenically unsaturated isocyanurates comprising reacting polyisocyanate with a monohydric alcohol containing a vinylidene group in the presence of a copper salt to form an isocyanate-containing urethane and then trimerizing the isocyanate-containing urethane to form an ethylenically unsaturated isocyanurate. The ethylenically unsaturated isocyanurate may be homopolymerized or copolymerized with ethylenically unsaturated monomers to form high molecular weight polymers having excellent physical properties.

US Patent:
44043953, Sep 13, 1983
Filed:
Jun 21, 1982
Appl. No.:
6/390662
Inventors:
Kenneth H. Markiewitz - Wilmington DE
Assignee:
ICI Americas Inc. - Wilmington DE
International Classification:
C07C 6726
US Classification:
560209
Abstract:
An improved process for the production of hydroxy alkyl acrylates or hydroxy alkyl methacrylates which comprises adding an alkylene oxide to a solution of acrylic or methacrylic acid, at least 0. 05% by weight of acid of chromium trioxide catalyst and at least 5% by weight based on acid of hydroxyalkyl acrylate or hydroxyalkyl methacrylate.

C08F 2600
C08F11600
US Classification:
526215
Abstract:
Ethylenically unsaturated monomers susceptible to free radical polymerization may be polymerized by contacting the monomers with an initiating compound having the formula: ##STR1## wherein R. sub. 1 is a substituted or unsubstituted aryl radical.

Esters Of Carboxy Amino Phenyl Isocyanurates And Vinylidene Carbonyl Oxy Alkanols

View page
US Patent:
41951468, Mar 25, 1980
Filed:
Jul 10, 1978
Appl. No.:
5/923265
Inventors:
Kenneth H. Markiewitz - Wilmington DE
Alfred J. Restaino - Wilmington DE
Assignee:
ICI Americas Inc. - Wilmington DE
International Classification:
C08G 1867
US Classification:
526261
Abstract:
Disclosed are unsaturated isocyanurates of monourethanes of an aromatic polyisocyanate and a vinylidene carbonyl oxy alkanol characterized by one of the following formulae: ##STR1## wherein R. sub. 1 is hydrogen or an alkyl group containing from one to four carbon atoms, R. sub. 2 is hydrogen, alkyl containing from 1 to 12 carbon atoms, or a chlorinated, brominated, or fluorinated alkyl group containing from 1 to 12 carbon atoms, R. sub. 3 is hydrogen, alkyl containing from 1 to 12 carbon atoms, or a chlorinated, brominated, or fluorinated alkyl group containing from 1 to 12 carbon atoms, R. sub. 4 is hydrogen, methyl or ethyl, and n is from one to four, with the proviso that R. sub. 2 and R. sub. 3 on adjacent carbon atoms are not both alkyl or chlorinated, brominated, or fluorinated alkyl. The unsaturated isocyanurates may be homopolymerized or copolymerized with ethylenically unsaturated compounds to form isocyanurate polymers having excellent physical properties at high temperatures.
