Copolymers, diglycidyl ether

For example, the block copolymers can be modified with a vinyl monomer [281 ]. In addition, diglycidyl ethers [282], that is, precondensates for epoxides, can be used as modifiers. Another possibility is modification with polyamines. [Pg.333]

Block polymers or copolymers of ethylene oxide and 1,2-propylene oxide can be chain extended or crosslinked, respectively, with diisocyanates, dicarboxylic acids, formaldehyde, and diglycidyl ethers [108]. [Pg.334]

Crosslinking can be achieved also, if the polyamine is modified with a vinyl monomer [283-285], Such mixtures are substantially free of copolymers derived from a polyoxyalkylene glycol and a diglycidyl ether. [Pg.341]

Abstract Porous copolymers have been prepared by suspension-emulsion polymerization of divinylbenzene with styrene or some methacrylic monomers di(methacryloyloxymethyl)naphthalene, methacrylic ester of p,p -dihydroxy-diphenylpropane diglycidyl ether, and dimethacrylglycolethylene in the presence and absence of chemically modified fillers (fumed silicas with grafted methyl and silicon hydride groups). The results of investigations of the unfilled and filled polymeric systems by IR and 13C NMR spectroscopies combined with AFM are presented. [Pg.103]

The third type of composition is exemplified by acrylate- and methacrylate-ester derivatives of epoxy resins combined with a photoinitiator 1. Epoxy prepolymers (e. g., glycidyl methacrylate-allyl glycidyl ether copolymers or Ciba ECN 1299) combined with a photosensitive aryldiazonium compound (e.g., -nitrobenzenediazonium hexaflourophosphate) (38,39) 2. Epoxy prepolymers (e.g., a diglycidyl ether of disphenol A-(3,4-epoxycyclohexyl)-methyl-3,4-epoxycyclohex-anecarboxylate-alkyl glycidyl ether mixture) combined with a photosensitive aryldiazonium compound (e.g., -chlorobenzenediazonium hexaflourophosphate) and l-methyl-2-pyrrolidone gelation inhibitor (40) ... [Pg.178]

The copolymerization of 1,2,4-trioxane with the diglycidyl ether of 1,4-dihydroxy diphenyldimethylmethane (catalyzed by BF30Et2 in nitrobenzene) was studied and found to proceed via the tertiary oxonium mechanism <1996MI23>. In the range 30-60 C, a linear copolymer with high alkali and thermal stability could be obtained... [Pg.596]

Both epoxidised oils have also been copolymerised with the diglycidyl ether of bisphenol A to give networks with better mechanical properties [7, 8]. For example, a copolymer containing 10 wt% of epoxidised castor oil prodnces an epoxy resin with better interfacial mechanical properties, and addition of a large amount of soft-segments resnlts in a decrease in the crosslink density and an increase in the tonghness of the final copolymer. [Pg.35]
