Hydrocarbon plastics Plastics composed of resins consisting of carbon and hydrogen only. 

These materials are hydrolytically unstable and weaken when stored in water for a week (Bryant Wing, 1976b). Prosser, Groffman Wilson (1982) found that calcium and hydroxide ions and salicylates were released and that the rate of release was controlled by the plasticizer used in the cement formulation. Hydrophilic sulphonamide plasticizers allowed ready ingress of water and promoted decomposition, whereas the hydrophobic hydrocarbon plasticizer repelled water and retarded hydrolytic decomposition. 

A patented process involves pre-reacting the hydrocarbon plasticizer with a small amount of molten sulfur at the manufacturing plant to form a concentrate which is shipped to the work site. At the site it is mixed with the heated aggregate and additional sulfur to reach the desired binder level fine filler is added, if necessary, and the molten mass is mixed and ready...

The binder contains 15—45% polymeric material, such as poly (vinyl acetate) or polyfvinyl chloride) with the lower alkyl esters of NC and 65— 85% oxygenated hydrocarbon plasticizers (such as lower alkylene glycols their oxalates, maleates, diglycolates or nitrodiphenyl ethers, etc). E.g. AN 78, Prussian Blue 3, N-amino-alkylmorpholine 3) binder 12, carbon black 3 MgO I%]...

Materials such as polyolefin and polyfluorinated hydrocarbon plastics present special difficulties for the technologists concerned because of the problems of wetting. (With these, bulky methyl or fluoroalkyl groups at the surfaces prevent close contact between the molecules.)... 

The preparation of foams of PCHE and copolymers has also been claimed [79]. A combination of a low-boiling hydrocarbon (butane) foaming agent and a higher boiling hydrocarbon plasticizer (toluene) were used to prepare foams. The increased heat distortion temperature of PCHE has been proposed to lead to utility in insulating foams for hot water pipes and similar applications. In addition, the superior weatherability of this material would allow use in applications in which the product was subjected to UV exposure. 

Most commodity hydrocarbon plastics are suitable for pyrolysis. Generally the larger the substituent in the side chain, the easier the plastic can be degraded. The order of increasing side chain size is polyethylene<polyvinyl chlorideProblems with many pre-existing plastic cracking technologies include ... 

The depolymerization catalyst possesses cations that make it act as an ion exchanger. Before the hydrocarbon plastics begin to thermally crack, they are dechlorinated and dehalogenated by neutralization by the ion exchanger.

Hydrocarbon plastics n. Plastics based on resins composed of hydrogen and carbon alone. Note—Oxygen and other elements may be present as impurities in the resins, less than 1% by wt. 

His patents (many with coinventors) were concerned with many subjects, including a leavening process, refining hydrocarbons, plastics, manufacture of alkyl nitrates, lubricants, additives, corrosion-proof liners, diesel fuel, alcohol-gasoline compositions. plasticizers, stabilized polymers, paving compositions, seed treatment, rocket propellent, and encapsulated oxidants. 

Some pigments have hydrophobic surfaces whilst others are hydrophilic. Consequently the former are more easily dispersed in organic media of low polarity such as hydrocarbon plastics, but the latter will be wetted more easily by water and highly polar media. For example, Phthalo Blue, which is hydrophobic, is used in plastics. 

Crack formation increases with the degree of unsaturation. Crack propagation rate decreases with increasing degree of crosslinking critical strain decreases. Crack formation is preferentially Initiated in areas of higher local surface strain. Very high loads of carbon black or other Alters thus can result In intense crack formation. Factors (such as hydrocarbon plasticizers) that increase elasticity also tend to increase crack formation [697].
