Guenter,
try www.matweb.com if you know the name of the particular resin you're
looking for.
Here's an example of one I found (it's got a lot of info, besides CTE, and
it's easier to read on the web site than here):

Subcategory: Diallyl Phthalate (DAP); Thermoset; 

Key Words: Rogers DAP; 

Material Notes: Data provided by the manufacturer, Rogers Molding Materials
Division, 1998.

Ortho Resin Isomer (DAP). Used for critical, high-performance military and
commercial electrical components where long-term reliability is demanded.
