Problems solved by technology

Usually, as hairspray compositions hold the hair for longer, the hair feels hard to the touch and is therefore not as pleasing

Embodiment 1

[0149] poly(tert-butyl acrylate-co-methoxyethyl acrylate-co-acrylic acid)-graft-[poly(n-propyl methacrylate-co-methacrylic acid); poly(dimethylsilyl Synthesis of oxane)] copolymers

Embodiment 2

[0152] Synthesis of poly(tert-butyl acrylate-co-methoxyethyl acrylate-co-methacrylic acid)-graft-poly(n-propyl methacrylate-co-methacrylic acid) copolymer

[0153] Into a round bottom flask equipped with a reflux condenser, temperature controller, mechanical stirring device, and under a slight argon pressure (8 psi), was charged acetone (0.5 L), tert-butyl acrylate (42.4 g), acrylic acid-2 - Methoxyethyl ester (29 g), methacrylic acid (9 g) and vinylphenyl terminated (n-propyl methacrylate-co-methacrylic acid) macromonomer (20 g) (obtained from Example 2) . The solution was stirred until all components were dissolved, then heated to 60°C. Azobisisobutyronitrile (0.5 g) was added to the system. After 10 hours, the solution was cooled and precipitated in water to give a graft copolymer.

Abstract

An adhesive copolymer and personal care composition thereof, said copolymer being characterized by an organic polymeric backbone wherein said backbone has a Tg of from 0 DEG C to 45 DEG C wherein said copolymer comprises one or more side chains grafted thereon consisting of acrylic and methacrylic monomer units wherein (each of) said side chains have a Tg of greater than 50 DEG C-200 DEG C wherein the number average molecular weight of said side chain is greater than 1000.

Description

technical field [0001] This invention relates to toughened grafted polymers. Background of the invention [0002] Cosmetic compositions, such as lotions, creams, lotions, packs, cosmetics (eg, foundations, lipsticks, eye shadows, etc.), and hair care compositions are used to enhance the appearance of a person. Many personal care products contain various resins, gums and adhesive polymers. Polymers are used for a variety of purposes, including thickening, sensory properties, film-forming ability, effective deposition, effective penetration and hair fixation, among others. Research has therefore continued to develop polymers with improved properties for use in personal care products. For example, the need to keep hair in a particular shape is widespread. The most common method of accomplishing this is by applying a styling composition to wet hair after shampooing and / or conditioning, or to dry, styled hair. These compositions provide temporary styling benefits and can be r...
