The present invention relates to a catalyst, which is an organic component with electron withdrawing substituents and to compositions with such catalyst and at least one benzoxazine component, and the use of such compositions in adhesives, sealants and coatings.
摘要:
Polymerizable combinations, comprising at least one first component selected from the group of benzoxazine monomers and at least one second component selected from the group of aromatic esters are described. Furtheron the use of aromatic esters as additives to benzoxazine monomers as well as methods of coating a device by heating the above mentioned combination, and a device, coated by that way is explained.
摘要:
A method for production of an N-carboxy amino acid anhydride with efficiency is provided. The method for production of an N-carboxy amino acid anhydride includes a step of reaction of an amino acid organic salt compound with a carbonic acid diester.
