Abstract
Copolymers are formed from 2,2,4-trimethylpentyl-1,3 -dimethacrylate (TMPD) and at least one other vinylidene or vinyl monomer. Specified comonomers are styrene, o-methylstyrene, m-methylstyrene, 2,4-dimethyl styrene, o-ethylstyrene, vinyl chloride, vinylidene chloride, acrylonitrile, 2,2,4-trimethyl-3-hydroxypentyl methacrylate and esters of formula <FORM:1110033/C3/1> wherein R1 is hydrogen or methyl and R is an alkyl group of 1 to 8 carbon atoms, an alicyclic group of 4 to 8 carbon atoms or an aryl or aralkyl group of 6 to 12 carbon atoms. For example R may be a cyclobutyl, cyclopentyl, phenyl, a -naphthyl or b -naphthyl group. The monomers are heated together to e.g. 40 DEG to 160 DEG C. The mixture may be cast into a film or mould either before heating or after partial reaction. In the latter case the copolymer may be cured by heating after casting. The monomer other than T.M.P.D. may be partially polymerized prior to addition of the T.M.P.D. In Example 1 a copolymer of T.M.P.D. and methyl methacrylate is prepared by polymerizing the latter to about 25% conversion and reacting the T.M.P.D. with the resulting syrup; in Example II 2,2,4 - trimethyl - 3 - hydroxypentyl methacrylate is also added to the methyl methacrylate syrup. In other examples terpolymers of T.M.P.D., (1) methyl methacrylate and (2) methyl acrylate, (3) ethyl acrylate, (4) n-butyl methacrylate, (5) n-butyl acrylate, (6) isobutyl acrylate, (7) 2-ethylhexyl methacrylate, (8) 2-ethylhexyl acrylate, (9) ethyl methacrylate and (10) isopropyl methacrylate are prepared. Copolymers of T.M.P.D. and (12) styrene, (13) o-methylstyrene, (14) m-methylstyrene, (15) 2,4-dimethylstyrene, (16) o-ethylstyrene, (17) vinyl chloride, (18) acrylonitrile and (19) vinylidene chloride are produced by reacting the monomers with t.-bu. hydroperoxide as catalyst. In Example 20 T.M.P.D. and 2,2,4-trimethyl-3-hydroxypentyl methacrylate are copolymerized using benzoyl peroxide as catalyst. In Examples 21 and 22 the comonomer is (21) cyclohexyl methacrylate and (22) a -phenylethyl methacrylate.
