Pyrolysis products of chlorinated polyethylene contain molecules similar to those found in polyethylene pyrolysates and, in addition, compounds similar to that obtained from vinyl chloride (significant amount of HCI). Chlorosulfonated polyethylene typically contains only about 1.5% sulfur, but sulfur-containing compounds such as SO2 can be detected among its pyrolysis products. The distribution of chlorine atoms in chlorinated polyethylene has been investigated using Py-GC [55, 56]. The polymer was considered equivalent with a terpoiymer poly[ethylene-co-(vinyl chloride)-co-(1,2-dichloroethylene)]. The level of specific degradation products such as aromatic molecules (benzene + toluene + styrene + naphthalene), chlorobenzene, and dichlorobenzenes correlates well with the carbon/chlorine ratio in the polymer. [Pg.296]

Examples of copolymers with practical use between two different carbonates are poly[2,2-propanebis(4-phenyl)carbonate]-Woc/c-poly[2,2-propanebis[4-(2,6-dimethylphenyl)]carbonate], poly [1,1-cyclohexane bis(4-phenyl)carbonate]-co-[2,2-propane bis(4-phenyl)carbonate], and poly [1,1-dichloroethylene bis(4-phenyl)carbonate]-co-[2,2-propane bis(4-phenyl)carbonate]. Examples of copolymers between a carbonate and an ester are poly[4,4 -(1-methylethylidene)bis[phenol]-co-1,3-benzenedicarboxylic acid-co-carbonic acid], poly[4,4 -(1-methylethylidene)bis[phenol]-co-1,4-benzenedicarboxylic acid-co-carbonic acid], etc. Other known copolymers include poly[2,2-propanebis(4-phenyl)carbonate]-b/oc/(-poly(ethylene oxide), poly[2,2-propanebis(4-phenyl)carbonate]-Woc/c-polysulfone, poly[2,2-propanebis(4-phenyl)carbonate]-b/oc/c-poly(dimethylsiloxane), poly[2,2-propanebis(4-phenyl)carbonate]-b/oc/c-poly(methyl methacrylate), etc. These copolymers have in general good thermal resilience and decompose similarly to other polycarbonates [23]. [Pg.566]

Polyacetylene reacts with chlorine rapidly to give a white polymer that is equivalent to poly(l,2-dichloroethylene) and no stereospecificity has been reported on the chlorinated polymer. The addition of halogens is an important general reaction of carbon-carbon double bonds in a stereospecific and regiospecific sense. For instance, the electrophilic additions of chlorine to ethylene, buta-1,3-diene and hexa-l,3,5-triene have been shown to proceed by 1,2-trans (anti), 1,4-cis (syn) and 1,6-trans (anti) attack, respectively. This stereospecificity has been rationalized with a mixing rule of a-n orbital interaction. The reaction of a long conjugated polyene like polyacetylene with chlorine may produce an atactic chlorinated polyene, because random l,2n additions occur to result in a random addition product. ... [Pg.963]

Photo chlorination can achieve 90% conversion [156, 157]. Typical commercially chlorinated poly (vinyl chloride), however, has a chlorine content of 66-67%. The material contains methylene groups and is in effect a copolymer of vinyl chloride and 1,2-dichloroethylene. [Pg.593]

Low temperature chlorination. In one process, an aqueous dispersion of poly(vinyl chloride) (containing a swelling agent such as chloroform) is heated to about 50°C, illuminated and treated with chlorine. Under these conditions, substitution occurs mainly at the unsubstituted methylene groups so that s-dichloroethylene units are formed. Commercial chlorinated poly (vinyl chloride) has a chlorine content of about 66-67% and is thus, in effect, a copolymer of vinyl chloride and s-dichloroethylene (poly-s-dichloroethylene would have 73% Cl) ... [Pg.98]

Poly(vinyl acetate) is soluble in a wide range of solvents. It is soluble at room temperature in aromatic hydrocarbons such as benzene and toluene chlorinated hydrocarbons such as carbon tetrachloride, chloroform and dichloroethylene lower alcohols such as methanol and ethanol esters such as ethyl acetate and butyl acetate and ketones such as acetone and methyl isobutyl ketone. The polymer is resistant to greases and oils. [Pg.108]

Product specifications for some typical commercial grades of poly(vinyl formal) are given in Table 5.2. As the formal content increases there is a progressive increase in softening point, impact strength and hardness. The materials, being amorphous, are soluble in solvents of similar solubility parameter, such as dichloroethylene and dioxan as the acetate content increases, the polymers become more soluble in ketones, esters and glycol ethers. [Pg.114]
