POLYMER COMPOSITION AND MOULDED ARTICLE MADE FROM SAID COMPOSITION Russian patent published in 2012 - IPC C08L45/00 C08L23/16 C08L53/02 C08L25/10 C08L65/00 C08K5/00 

FIELD: chemistry.

SUBSTANCE: moulded article is made from a polymer composition containing 99-30 pts.wt cyclic olefin polymer (A); and 1-70 pts.wt soft copolymer (B) obtained through polymerisation of at least two monomers selected from a group consisting of olefins, dienes and aromatic vinyl hydrocarbons and having glass transition temperature not higher than 0°C. Said polymer composition also contains 100 pts.wt of the total amount of cyclic olefin polymer (A) and soft copolymer (B), 0.001-1 pts.wt radical initiator (C), 0-1 pts.wt polyfunctional compound (D) containing two or more radically polymerisable functional groups in a molecule, and 0.5-10 pts.wt nonionic or anionic antistatic additive (E). The moulded article, particularly a container, is used for work in pure production facilities when producing articles such as cassettes for semiconductor wafers.

EFFECT: moulded articles having high wear and impact resistance can be made from the polymer composition.
