Patent number: 5254665Abstract: Ammeline-melamine-formaldehyde resins (AMFR) containing from 5-100% ammeline were synthesized by the polymerization of the sodium salt of ammeline, which must be made in advance, melamine, and formaldehyde in basic medium (pH=9.2-10.0). In this copolymerization, it is possible to make uniform random AMFR resins with any mole ratio of ammeline salt to melamine. Preferably the AMFR resin will contain from 5-10% ammeline.

The polymer is prepared by free radical organic solution polymerization techniques. Synthesis of the polymers by this technique assures multiple hydroxyl functionality in all polymer chains thereby providing good cure response. The polymers are useful as binders in high solids coating compositions. When used with appropriate curing agents, the resultant coatings have good hardness, high gloss and distinctness of image, have good solvent and humidity resistance and are very resistant to acid etching.Preferred reactants are:(a) an alpha, beta ethylenically unsaturated carboxylic acid and(b) a glycidyl ester of the formula ##STR1## where R=a tertiary aliphatic hydrocarbon group of 4 to 26 carbon atoms.Type: GrantFiled: May 13, 1987Date of Patent: April 4, 1989Assignee: PPG Industries, Inc.Inventors: Suryya K. Das, Samuel Porter, Jr., Wayne H. Tyger

Patent number: 4736035Abstract: Heterocyclic styryl compounds are prepared by condensing nitrogen heterocyclic compounds such as trimethyl pyridine with dialdehydes and heterocyclic aldehydes such as furfural. These can be further reacted and chain extended with bismaleimides or polymaleimides. The compounds and their reaction products are useful to make heat resistant composites with various fibers such as graphite fibers.Type: GrantFiled: April 4, 1986Date of Patent: April 5, 1988Assignee: The Dow Chemical CompanyInventor: Paul M. Puckett

Patent number: 4656229Abstract: Two-part anaerobic adhesives and articles bonded therewith are disclosed. The adhesives comprise a first part component of free radical initiated polymerizable acrylic monomer(s) and a diaryl iodonium salt. A second part comprises a condensation reaction product of an aldehyde and a primary or secondary amine. The described curable adhesives are formed just prior to use where the second part containing the activator is brought in contact with the first part. Both the first part and second part component exhibit a high degree of stability when stored separately.Type: GrantFiled: December 2, 1985Date of Patent: April 7, 1987Assignee: National Starch and Chemical CorporationInventor: Wen B.
