| abstract |
A process for the preparation of a phenolic foam, which comprises forming a composition comprising a phenolic resin, a blowing agent, and an anhydrous curing agent and causing or allowing the composition to foam and cure, the blowing agent being insoluble in the resin and being capable of forming at least two distinct droplet size populations which are able to expand separately to form a cellular structure having two or more cell species substantially different in size. The foam prepared has a closed cell structure and retains a substantial proportion of blowing agent which can be selected to impart low K properties to the product. |
