Claims
- 1. A hot melt adhesive consisting essentially of a methoxymethylated nylon terpolymer of nylon 12 : nylon 6 : nylon 66, copolymerized in a weight ratio of 24-45 : 25-45 : 25-45, said nylon terpolymer having a melting point of less than 150.degree. C. and having a methoxymethylation ratio in the range of from 15 to 25%, wherein the methoxymethylation ratio is the ratio of nitrogen atoms bonded to methoxymethyl groups to the total number of nitrogen atoms contained in the nylon terpolymer.
- 2. An adhesive according to claim 1 containing from 0.5 to 8 weight percent, based on the weight of said terpolymer, of a hardener selected from the group consisting of tartaric acid, maleic acid, crotonic acid, malonic acid, succinic acid, oxalic acid, adipic acid, citric acid, o-, m- and p-hydroxybenzoic acid, 2,4-dihydroxybenzoic acid, 2-hydroxy-4-methoxybenzoic acid, hypophosphorous acid, p-toluenesulfonic acid and chromic acid anhydride.
- 3. An adhesive according to claim 1 in the form of a film having a thickness of from 5 to 50 microns.
- 4. A process for adhering together fibrous substrates which comprises placing between said substrates a film of adhesive as claimed in claim 3 and then pressing said substrates together at a pressure of 0.01 to 1 kg/cm.sup.2, at a temperature of 100.degree. to 160.degree. C. for 0.2 to 20 seconds so that said film melts and adhesively secures together said substrates.
- 5. A process for adhering together metal substrates which comprises placing between said substrates a film of adhesive as claimed in claim 3 and then pressing said substrates together at a pressure of 5 to 10 kg/cm.sup.2, at a temperature of 120.degree. to 180.degree. C. for 0.2 to 30 minutes so that said film melts and adhesively secures together said substrates.
