A SOLUBLE LINEAR COPOLYMER COMPOSED OF HYDROCARBON CHAINS HAVING AS ESSENTIAL EXTRANLINEAR SUBSTITUENTS, GLYCIDYL-TERMINATING AND MONOAMINOALKOXY-TERMINATING GROUPS, ANY OTHER OXYGEN-CONTAINING EXTRALINEAR SUBSTITUENT BEING ALIPHATIC AND TERMINATING IN AN ALKYL GROUP, SAID COPOLYMER BEING CONVERTED TO AN INSOLUBLE CROSSLINKED POLYMER BY REACTION OF SAID GLYCIDY GROUPS WITH SAID MONOAMINOALKOXY GROUPS UPON HEATING TO 50* TO 150*C. AND WHEREIN SAID COPOLYMER CONSISTS OF A POLYMERIZED MIXTURE OF 1% TO 99% OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF THE GLYCIDY ETHERS OF ALLYL AND METHALLYL ALCOHOLS AND THE GLYCIDYL ESTERS OF ACRYLIC AND METHACRYLIC ACIDS, 1% TO 99% OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF THE BETA-DIETHYLAMINOETHYL AND BETA-DIMETHYLAMINOETHYL ESTERS OF ACRYLIC AND METHACRYLIC ACIDS AND BETA-VINYLOXYETHYLAMINE.
