Abstract: 589,650. Polyallyl esters. SHELL DEVELOPMENT CO. Aug. 16, 1944, No. 15624. Convention date, Aug. 11, 1943. [Class 2 (iii)] [Also in Group VIII] Polyallyl type esters or polyallyl type alcohols obtained by hydrolysis or alcoholysis' of polyallyl type esters are heated with unsaturated acids, or a mixture of such acids, or anhydrides or acid halides of unsaturated acids. Polyallyl type esters specified are polymeric allyl formate, acetate, propionate, butyrate, isobutyrate, beta-methallyl acetate, beta chlorallyl acetate, beta ethallyl formate, beta phenyl allyl acetate, beta methoxy allyl acetate, beta chloromethylallyl acetate, allyl benzoate, toluate, salicylate, glycollate, methoxyacetate, beta methallyl chloracetate, allyl beta chlorpropionate, lactate, naphthenate, alpha hydroxy isobutyrate, acetyl glycollate, stearate, levulinate, ethoxy formate, naphthoate, abietate, diallyl malonate, succinate, adipate, maleate, phthalate, beta methallyl chlorobenzoate, chloroacetate, butyrate and alpha methallyl acetate, alpha phenylallyl acetate, beta methallyl phenoxyformate, diallyl diglycollate, dilactate, dihydracrylate, dimethallyl diglycollate, dicrotyl dilactate, allyl halides and allyl type esters of ortho acids of boron and silicon.. The polymers of the allyl-type esters or allyl type alcohols obtained therefrom may be air blown, hydrogenated or treated with sulphur dioxide before heating with the unsaturated acid. 'Unsaturated acids specified are palmitoleic, oleic, linoleic, linolenic, arachidonic, clupanodonic, elaeostauric, licanic acids, 9-11 linoleic, octadecadienic and ricinic acids and commercial mixtures obtained from chia, hempseed, linseed, perilla, sunflower, soyabean, walnut, poppyseed, sunflower oils, oiticica, Japanese wood, walnut seed, rubber seed, dehydrated castor and tall oils. Saturated acids and alcohols may be present. Driers may be added such as red lead, litharge, manganese dioxide, cobalt, lead and manganese resinates, linoleates and naphthenates, manganese, calcium and zinc borates, lead acetate and carbonate, blowing with oxygen, ozone, hydrogen peroxide, sodium, calcium, barium and benzoyl peroxides, perborates and percarbonates: Dyes, fillers, solvents and artificial and natural resins may be added such as resin, colophony, shellac, copal, dammar gun, pitch, asphalt, protein plastics, cellulose derivatives, phenol aldehyde, urea aldehyde, alkyd, super polyamides and ester resins, polymers of vinyl, allyl and methallyl esters of acetic, propionic and butyric acids, of methyl, ethyl and propyl esters of acrylic and methacrylic acids, styrene, alpha methyl styrene, ethylene,of vinyl and vinylidene halides, of allyl alcohol and halides, polyvinyl acetals and after chlorinated polyvinyl chloride, polymers of vinyl, allyl and methallyl esters of oxalic, malonic, succinic, glutaric, citric, tartaric, phthalic, isophthalic, naphthalene dicarboxylic, acrylic and methacrylic acids, vinyl, allyl, methallyl and cyclohexinyl esters of ortho acids of boron and silicon, sulphuric and phosphoric acids, polymers of acrylic and methacrylic esters of glycol, diethylene glycol, triethylene glycol, trimethylene glycol and glycerol, poly ethers of vinyl, allyl and methallyl with glycol, triethylene glycol, trimethylene glycol, diethylene glycol and glycerol, polymers of vinyl, allyl, methallyl and crotyl diethers, polymers of butadiene, pentadiene, mono vinyl acetylene and divinyl acetylene. Esterification of the polyallyl type alcohols may be carried out in the presence of water admixed with kerosene, high boiling ethers or solvent naphthas. Specification 566,344 is referred to.
