Definitions
- This invention relates to polyesters prepared from certain substituted hydrocarbon diols and/or derivatives of said substituted hydrocarbon diols, and polyfunctional carboxylic acids and/or acid anhydrides.
- the polyesters are useful in preparing coatings, adhesives, inks, and sealants that are cured with a variety of crosslinking agents.
- Polyesters are well known in industry. They are formed when a glycol and a dicarboxylic acid or acid anhydride react by esterification and/or addition in the case of an anhydride to form long- chain molecules that are either hydroxyl or carboxyl terminated. Polyesters are usually designed so most terminal or end groups are hydroxyl in nature. Polyesters such as the poly (ethylene terephthalates) are useful in spinning fibers.
- polyesters such as poly( ethylene glycol/adipate), poly( diethylene glycol/adipate), poly(butylene/adipate), poly(hexanediol/adipate) and similar polyesters are used as soft segments in polyurethanes, and as flexible components of coatings, inks, sealants, and adhesives that are cured with various crosslinking agents.
- polyesters One well known deficiency of the polyesters is their tendency to hydrolyze when used. This leads to a shortened useful lifetime for products made from them, particularly when the polyester articles are exposed to acidic or basic conditions.
- polyesters and other molecules developed for coatings that will be formulated and applied as high solids coatings for a combination of environmental, ecological, and energy conservation reasons is a poor balance of properties.
- the requirement for high solids formulations is driven by both federal and state regulations.
- the lack of a good balance of properties is usually related to the low molecular weight oligomers/polymers that must be prepared and used to achieve the sufficiently low viscosity needed for formulated systems that are high solids in nature and that have a low volatile organic content.
- polyesters and coatings derived from them that have a good balance of properties so that energy can be conserved through use of less diluent solvent and so that federal and state regulations as well as community standards can be met.
- Polyesters that would have improved water, acid, and other chemical resistance over those presently known would be highly desirable products for the preparation of hydrolytic resistant coatings, inks, adhesives, and sealants.
- Features such as higher solids with balanced properties and low temperature cure features are highly desirable characteristics in coatings currently needed and for the future.
- Particularly desirable would be acid resistant coatings prepared from polyesters, since they would be important components in acid-rain resistant coatings.
- Such coatings are useful as automotive clear coatings that are used to cover color coats in what is known as clear coat/color coat systems as well as in other end uses including outdoor signs, functional and decorative coatings for metal and plastics, as for example in outdoor signs, coatings for electronic parts, and similar end uses.
- polyesters of various molecular weights and/or viscosities can be prepared from certain substituted hydrocarbon diols and/or derivatives of said substituted hydrocarbon diols, polyfunctional carboxylic acids and/or acid anhydrides, and optionally other polyols.
- the substituted hydrocarbon diols are comprised of primary hydroxyl groups and 5 or more carbon atoms in which the primary hydroxyl groups are separated by 3 or more carbon atoms linearly arranged and in which at least one of said carbon atoms linearly arranged is a disubstituted carbon atom or at least 2 of said carbon atoms linearly arranged are monosubstituted carbon atoms.
- the polyesters of this invention include both saturated and unsaturated polyesters.
- This invention also relates to a process for preparing polyesters which comprises condensing a substituted hydrocarbon diol comprised of primary hydroxyl groups and 5 or more carbon atoms in which the primary hydroxyl groups are separated by 3 or more carbon atoms linearly arranged and in which at least one of said carbon atoms linearly arranged is a disubstituted carbon atom or at least 2 of said carbon atoms linearly arranged are monosubstituted carbon atoms, and/or a derivative of said substituted hydrocarbon diol, with a polyfunctional carboxylic acid and/or an acid anhydride and optionally other polyols to form said polyester.
- the particular substituted hydrocarbon diols and derivatives used have the characteristics of hydrophobicity, nonhydrolyzability , and lack of chemical attack and these characteristics are carried through to the polyester and to crosslinked coatings or other articles made from them.
- a number of the polyesters described herein may contain asymmetric carbon atoms due to the particular diols employed in their manufacture. Such polyesters will have the special property of optical activity which makes them useful as frequency doublers of laser beams and the like.
- the polyesters of this invention are useful in the preparation of polyurethane foams and elastomers, fibers, coatings, adhesives, inks, sealants that are cured with various curing agents, as well as in other end uses.
- This invention overcomes many of the disadvantages of conventional polyester resins by making unique polyesters that have improved water, acid, and other resistance over those presently known and imparting this resistance to products made from them such as coatings, inks, adhesives, sealants, fibers, polyurethane foams and elastomers, and the like.
- polyesters are prepared by condensing a substituted hydrocarbon diol comprised of primary hydroxyl groups and 5 or more carbon atoms in which the primary hydroxyl groups are separated by 3 or more carbon atoms linearly arranged and in which at least one of said carbon atoms linearly arranged is a disubstituted carbon atom or at least 2 of said carbon atoms linearly arranged are monosubstituted carbon atoms, and/or a derivative of said substituted hydrocarbon diol, with a polyfunctional carboxylic acid and/or an acid anhydride to form an essentially hydroxyl-terminated polyester product.
- substituted hydrocarbon diols useful in this invention can be represented by the formula:
- R'l is a substituted hydrocarbon residue having 5 or more carbon atoms in which the primary hydroxyl groups are separated by 3 or more carbon atoms linearly arranged and in which at least one of said carbon atoms linearly arranged is a disubstituted carbon atom or at least 2 of said carbon atoms linearly arranged are monosubstituted carbon atoms.
- Preferred substituted hydrocarbon diols useful in this invention include substituted 1,3-propanediols represented by the formula: R' 2 I HOCH 2 — C-CH 2 OH
- R'2 and R'3 are the same or different and are linear or branched alkyl having from 1 to 4 carbon atoms.
- the hydrocarbon diols useful in this invention do not include liquid hydrocarbon diols that are comprised of primary hydroxyl groups and 8 or more carbon atoms in which the primary hydroxyl groups are separated by 4 or more carbon atoms linearly arranged and in which at least one of said carbon atoms linearly arranged is a disubstituted carbon atom or at least 2 of said carbon atoms linearly arranged are monosubstituted carbon atoms, said liquid hydrocarbon diol existing as a liquid at a temperature of 35°C or less.
- the substituted hydrocarbon diols useful in this invention can be prepared by a process which comprises subjecting a first reaction mixture comprising a substituted hydroxyaldehyde to hydrogenation in the presence of a hydrogenation catalyst to produce a second reaction mixture comprising said substituted hydrocarbon diol.
