Title (EN) SILICONE RESIN-LINEAR COPOLYMER AND RELATED METHODS
(FR) COPOLYMÈRE LINÉAIRE-RÉSINE DE SILICONE ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) A silicone resin-linear co-polymer is disclosed. The silicone resin-linear copolymer includes a resinous structure having the general formula (1): (R1R2R3SiO1/2)x(R4SiO3/2)y (1) wherein each R1, R2, R3 and R4 is an independently selected substituted or unsubstituted hydrocarbyl groups, with the proviso that in one molecular at least two of R1, R2 and R3 are aryl groups; and x and y are each from >0 to <1 such that x+y=1; and a linear structure having the general formula (2): (R5R6SiO2/2) (2) wherein R5 and R6 are each independently selected substituted or unsubstituted hydrocarbyl groups. End use applications and related methods of the silicone resin-linear copolymer are also disclosed.
(FR) L'invention concerne un co-polymère linéaire-résine de silicone. Le copolymère linéaire-résine de silicone comprend une structure résineuse ayant la formule générale (1) : R1R2R3SiO1/2)x(R4SiO3/2)y (1) dans laquelle chaque R1, R2, R3 et R4 représente un groupe hydrocarbyle substitué ou non substitué indépendamment choisi, à condition que dans une molécule au moins deux parmi R1, R2 et R3 représentent des groupes aryle; et x et y sont chacun compris entre >0 et <1 et tels que x + y = 1; et une structure linéaire ayant la formule générale (2) : (R5R6SiO2/2) (2) dans laquelle R5 et R6 représentent chacun indépendamment des groupes hydrocarbyle substitués ou non substitués choisis indépendamment. L'invention concerne également des applications d'utilisation finale et des procédés associés du copolymère linéaire-résine de silicone.
