Solid state polymerization of relatively low I.V. polyester using a water-soluble anti-stick agent.

Solid state polymerization

Increasing the molecular weight of polyesters by reaction with polyfunctional acyl compounds having at least two alkylidene malonate groups.

Malonate ester chain coupling of polyesters

High strength structural metal-to-metal bonds can be achieved in 10 to 15 seconds by placing a resinous polyamide capable of imidizing between the metal surfaces to be bonded and heating the composite to a temperature sufficiently high (.gtoreq. 400.degree.F) to induce imidization.
