Abstract
The present disclosure relates to an encapsulant film made from a curable composition comprising: (A) a polyolefin polymer; (B) an organic peroxide; (C) a silane coupling agent; and (D) a co-agent comprising a monocyclic organosilazane of formula (I).
Claims17
A curable composition for forming an encapsulant film, wherein the composition comprises:
- (a) a polyolefin polymer;
- (b) an organic peroxide;
- (c) a silane coupling agent;
- and
- (d) a co-agent comprising a monocyclic organosilazane of formula (I):
- [R1,R2SiN(R3)2/2]n (I), wherein subscript n is an integer greater than or equal to 3;
- each R1 is independently a (C2-C4)alkenyl;
- and each R2 and R3 is independently H, (C1-C4)alkyl, phenyl, or R1.
