| titleOfInvention | Improvements in or relating to acrylic polymers and copolymers |
| abstract | An alkylated or haloalkylated polymer having a molecular weight of 10,000-1,000,000, which is soluble in alcohols and aliphatic hydrocarbons, is prepared by heating a homopolymer derived from an acrylic ester monomer or a copolymer derived from 5-95% by weight of an acrylic ester monomer and 95-5% by weight of a non-heterocyclic monoethylenically unsaturated monomer, with an a -olefin or a fluoro- or chlorofluoro-derivative thereof, in solution in an organic solvent common to the polymer and olefin or haloolefin in the presence of 0.025-0.3 mole of an organic peroxide catalyst per mole of the olefin at a temperature of 80-200 DEG C., the molar ratio of the olefin or haloolefin to the acrylate ester moiety equivalent being from 0.05 : 1 to 12 : 1. The polymer or copolymer is preferably derived from an acrylate of a C1-C18 alkanol or C3-C6 alkoxyalkanol. The non-heterocyclic monomer may be a vinyl ester, a methacrylate ester, an a -haloacrylate ester, a -ethylacrylic acid, vinyl isobutyl ether, acrylonitrile, methacrylonitrile, acrylamide, methacrylamide or an N-alkyl or N-aryl acrylamide. The polymers may be obtd. by polymerizing the corresponding monomer(s) in a solvent such as an alkanol, diol, diacetone alcohol, ethylene glycol monomethyl ether acetate or methylene chloride using an initiator such as an organic peroxide or azobisisobutyronitrile. The aforementioned solvents also serve as the medium for alkylation. Peroxides for use as initiator and/or for the alkylation reaction include t-butyl perbenzoate, dibenzoyl peroxide, benzoyl hydroperoxide, t-butyl hydroperoxide, t-butyl perphthalic acid, p-chlorobenzoyl peroxide, t-butyl peracetate, di-t-butyl peroxide, cumene peroxide, di-t-amyl peroxide and lauroyl peroxide. The alkylating agent may be any a -olefin having a molecular weight from 28 (ethylene) to 2500 (for polybutenes) and may include mixtures obtained by cracking petroleum wax; several examples are given. Alternatively, a fluoro- or chlorofluoro-a -olefin may be used, e.g. dichlorovinylidene fluoride, chlorovinylidene fluoride, chlorotrifluoroethylene, tetrafluoroethylene or vinylidene fluoride. The alkylated polymers are suitable for use in hair sprays, as dispersing agents in fuel oils or lubricating oils, and as fire-retardants. |
