NEED MONOMERS OR POLYMERS FOR A SPECIFIC JOB?

Why not check with Borden's Monomer-Polymer Laboratories? Over 600 tailor-made monomers are avail­able for specific appl icat ion, such as crosslînking, polyelectrolyte, internal plasti-cization, water-solubility, dyeability, specif­ic functional character, enhanced adhesion, high temperature resistance, low tempera­ture flexibility, and chemical resistance. ,. Polymers can be custom-made in emulsion,

suspension, solutions, or bulk to fit your spe­cific need. Exact control to your specifica­tions is provided by infra-red or ultra-violet spectroscopy, electron microscopy, light scat­tering measurements, and other instrumental techniques.

Utmost secrecy is provided as can be attested by the number of large and small industrial corporations that repeatedly take advantage of this confidential service.

Monomers or polymers are available in lots from one pound to one ton.

Send for literature and working samples.

Y O U SAVE MONEY WITH MeG-BASED POLYETHERS

Chart shows: Rigid foam with excellent foam properties can be obtained with lower hydroxyl numbered MeG-based polyethers; thus, less of the more expensive isocyanate is required. The cyclic structure and tetra-functionality of MeG is responsible. * (Based on Isocyanate and MeG-Polyether)

MeG says: Ideal, too, for prep­aration of alkyd res­ins, flexible ure-thanes, esters, sur­factants and resin modification!

•Please send me working samples of methyl glucoside. I'd like to have more technical details on methyl glucoside for preparation of:
