Abstract: The invention pertains to capryloyloxyalkyl acrylates of the general formulaCH.sub.2 .dbd.CH--CO--O--R--O--CO--(CH.sub.2).sub.6 --CH.sub.3,where R is an alkylene group with 2 to 6 carbon atoms, their polymers and copolymers containing structure units of the general formula ##STR1## where R is alkylene group or different alkylene groups with 2 to 6 carbon atoms and the polymer contains either 100% of the capryloyloxyalkyl acrylate structure units or additional vinyl chloride structure units in the main chain or side chains.The invention also pertains to the method for preparation of capryloyloxyalkyl arcylate which consists in the esterification of hydroxyalkyl caprylate of the general formulaHO--R--O--CO--(CH.sub.2).sub.6 --CH.sub.3,where R has the above given meaning, with acrylic acid, its chloride, bromide or anhydride or of hydroxyalkyl acrylate of the general formulaHO--R--O--CO--CH.dbd.CH.sub.

Abstract: The invention relates to polymers and copolymers of pivaloyloxyalkyl methacrylates which contain structural units of the general formula ##STR1## where R.sup.1 is (CH.sub.2).sub.n.sbsb.1 --O (n.sub.1 =2 to 10) or (CH.sub.2 CH.sub.2 --O).sub.n.sbsb.2 (n.sub.2 =1 to 4) and to the method of their preparation and modification. The polymerization and copolymerization can be initiated by free-radical initiators of the peroxy type or by anionic initiators, e.g., alkali metal alkoxides or butyllithium, and carried out in a solution, bulk or suspension process in the presence of a crosslinking agent or without it. Anionic polymerization may result in stereoregular polymers or may be used for preparation of block copolymers by the "living" polymer technique. The polymers and copolymers can be modified by the partial or total conversion of the pivaloyloxyalkyl methacrylate units into hydroxyalkyl methacrylate units by selective hydrolysis, alcoholysis or other reaction.
