LATEX CONTAINING WATER AND STYRENE UNIT-COPOLYMER AND METHOD OF PRODUCING PRODUCTS THEREFROM Russian patent published in 2017 - IPC C08L53/02 

FIELD: chemistry.

SUBSTANCE: products are produced from latex containing water and a styrene unit-copolymer, where the styrene unit-opolymer contains 2 or more poly (vinylaromatic) units and, at least, one polymerized conjugated diene unit, where the weight-average molecular weight of the styrene unit-copolymer is from 170,000 up to 220,000, the weight-average molecular weight of the poly (vinylaromatic) units ranges from 9,000 to 14,000 and the content of the poly (vinylaromatic) units in the styrene unit-copolymer is in the range of 9 to 14% of the total styrene unit-copolymer, and a curing agent, a method comprising coating the surface with latex to form a film, where latex contains a curing agent. The invention also relates to a styrene unit-copolymer, which is particularly suitable for use in such a latex.

EFFECT: products with increased resistance to stretching and comfort.
