Described herein are circuit board substrates prepared from certain poly(aryl ethers) based on 4,4'-dichlorodiphenyl sulfone.

Novel poly(aryl ethers) useful for molding into a circuit board substrate

Described herein are novel poly(aryl ethers) based on 2,5-di-t-butylhydroquinone. These poly(aryl ethers) have excellent high temperature, oxidative and chemical resistance, as well as good melt-fabricability.

New polyarylethersulfone circuit board substrates

Polyarylether sulfones useful for molding into a circuit board substrate

The method of preparing a thermoplastic polyarylether polymer which comprises reacting a first monomer composition comprising an activated dihalobenzenoid compound and a dihydroxydiphenyl aliphatic monomer in a molar ratio of dihalobenzenoid compound to dihydroxybenzenoid compound of at least 1.2 to 1, adding to the product a second monomer composition comprising a dihydroxybenzenoid compound comprising at least one compound which is free of aliphatic moieties and polymerizing.

Production of aromatic amorphous thermoplastic poly aryl ether from

Novel photocurable compositions employing the addition of thiols to polymers having terminal vinyl-acetal functions, products prepared therefrom, and process for preparation thereof are disclosed. The cured products are films useful in coating floor tile, fabrics, and wooden articles.

Photocurable compositions

Photocurable compositions comprising a polythiol and a polyene derived

Diesters of succinic, glutaric, adipic, and phthalic acid with hexyloxyethoxyethanol or butoxyethoxyethoxyethanol are disclosed. They are useful as plasticizers with extended temperature ranges in elastomers.

Low temperature plasticizers for specialty rubbers consisting of

A novel group of amine formal polymers of the general formula: ##STR1## wherein R is hydrogen, --CH.sub.2 R' or ##STR2## R' is hydrogen or --CH.sub.2 R' and R' is hydrogen, alkyl or hydroxyalkyl, n is 1 to 8, m is 0 to 8 and R, R', and R' may be the same or different. The polymers may be prepared by reacting bis(haloethyl)formals with ammonia or primary amines and/or monoalkanolamines in the presence of aqueous alkali. The products may be used as, e.g., rust inhibitors, acid scavengers, antioxidants and epoxide and urethane curing catalysts. Certain of the polymers are especially useful as epoxide curing agents.
